‎First appearance of Renner's seminal paper containing what was to become known first as the Renner effect, later the Renner-teller effect. It was the first work to study the dynamic effects that go beyond the Born-Oppenheimer approximation, in which the nuclear and electronic motions in a molecule are uncoupled.Because Renner is the only author of the 1934 paper that first described the effect, it was long called the Renner effect. However, as Herzberg's prestigious books refer to it as the Renner-Teller effect (after Edward Teller), it is now more common to use both names.‎

There he took up the quantum, the Bohr theory, and the problem of X-ray spectra. After delivering a crushing blow to the faltering Sommerfeld-Debye theory, which deduced X-ray spectra from hypothetical intra-atomic mechanisms, Smekal, in competition with Dirk Coster and Gregor Wentzel, induced from the experimental data the number, arrangement, and allowed transitions between the atomic energy levels resulting in X-ray spectral lines.""

‎First appearance of this seminal paper which contains Rutherford's discovery of artificial transmutation. He here discovered, that the atomic nucleus (discovered by him in 1911) itself had a structure, when, by bombarding nitrogen with alpha particles, he produced THE FIRST ARTIFICIAL TRANSFORMATION OF AN ELEMENT INTO ANOTHER, and what was left after the bombardment had to be those of oxygen atoms. - Thus thus began the age of nuclear physics.""Rutherford was .. the first man ever to change one element into another as a result of the manipulations of his own hands. He had achieved the dream of the alchemists. He had also demonstrated the first man-made ""nuclear reaction"". By 1924 Rutherford had managed to knock protons out of the nuclei of most of the lighter elements."" (Asimov).""A few years before, Marsden had noticed scintillations on a screen placed far beyond the range of alpha particles when these particles were allowed to bombard hydrogen. Rutherford repeated the experiment and showed that the scintillations were caused by hydrogen nuclei or protons. This was easily understood, but when he substituted nitrogen for the hydrogen, he saw the same proton flashes. The explanation he gave in 1919 stands beside the transformation theory of radioactivity and the nuclear atom as one of Rutherford’s most important discoveries. This, he said, was a case of artificial disintegration of an element. Unstable, or radioactive, atoms disintegrated spontaneously"" but here a stable nucleus was disrupted by the alpha particle, and a proton was one of the pieces broken off."" (DSB).PMM 411.‎

‎First printing of Ruska and Knoll's two seminal papers which constitute the first theoretical and practical description of an electron microscope. This invention allowed researchers for the first time to view objects as small as the diameter of an atom. Not only did the discovery have profound influence on physics, it also revolutionized biological research, as it now became possible to distinguish individual molecules. Ruska received the Nobel Prize in physics in 1986 for his discovery regarding the electron microscope, which by the Committee was described ""as one of the most important innovations of the 20th century"".In 1933 the theoretical description presented in the present paper [1932] led Ruska to build a two-stage electron microscope with a resolution exceeding that of the optical microscope [described in the 1932 paper]. The technique behind it is largely built upon de Broglie's revolutionary theory regarding the wavelength of electrons. In 1931, working closely with Knoll, Ruska built the first electron lens, an electromagnet that could focus a beam of electrons, as if it were light. Using several such lenses, he was able to construct a prototype of an electron microscope, though with only the ability to magnify a meager 17 times. Yet, he had proven that the task was possible and he continued to improve his design. By 1933, Ruska's electron microscope, termed a transmission microscope, was much more powerful. The instrument worked by passing electrons through a thin slice of the specimen to be studied, which were then deflected to a photographic film emulsion or projected onto a fluorescent screen, generating an image at high magnification. In fact, the device was capable of magnifying specimens up to 10 times more than a contemporary light microscope.To build a commercial version of his microscope, Ruska was forced to briefly leave the academic world and delve into private industry. He joined the Siemens Company as an electrical engineer in 1937 and the company released its first marketable electron microscope, based on Ruska's design, in 1939.The volume contains many important contributions to 20th century physics, among others: Heisenberg, W. Über den Bau der Atomkerne. II. Pp. 156-64: This is the second paper in a series of three which presents Heisenberg's neutron-proton model. Shortly after Chadwick discoverd the neutron in 1932, Heisenberg developed a theory suggesting that atomic nuclei are composed of protons and neutrons, this introduced the concept of the nuclear exchange force and isotopic spin.

‎First printing of the paper which Rutherford and Royds gave the final proof that the alpha particle are atoms of helium. The present paper was read on November 3rd 1908 and published on the 19th. It was reprinted in Philosophical Magazine and that paper is dated November 13, 1908 and published February 1909.""After nearly a decade of labor, Rutherford was finally prepared to state... what the alpha particle really was ""We may conclude that an alpha-particle is a helium atom, or, to be more precise, the alpha-particle, after it has lost its positive charge, is a helium atom"". In a paper together with Royds, completed in November 1908, he was even more emphatic: ""We can conclude with certainty... that the alpha-particle is a helium atom... They had shown that a discharge sent through a volume in which alpha-particles from radium had been collected produced the characteristic helium spectrum !""(Pais ""Inward Bound"", p. 61).""Rutherford’s early conviction that the alpha particle was a doubly charged helium atom, but he had not succeeded in proving that belief. In 1908 he and Geiger were able to fire alpha particles into an evacuated tube containing a central, charged wire and to record single events. Ionization by collision, a process studied by Rutherford’s former colleague at Cambridge, J. S. E. Townsend, caused a magnification of the single particle’s charge sufficient to give the electrometer a measurable ""kick."" By this means they were able to count, for the first time accurately and directly, the number of alpha particles emitted per second from a gram of radium.This experiment enabled Rutherford and Geiger to confirm that every alpha particle causes a faint but discrete flash when it strikes a luminescent zinc sulfide screen, and thus led directly to the widespread method of scintillation counting. It was also the origin of the electrical and electronic methods of particle counting in which Geiger later pioneered. But at this time the scintillation technique, now proved reliable, was more convenient. This counting work also led Rutherford and Geiger to the most accurate value of the fundamental electric charge e before Millikan performed his oil-drop experiment. They measured the total charge from a radium source and divided it by the number of alphas counted to obtain the charge per particle. Since this figure was about twice the previous values of e. they concluded that the alpha was indeed helium with a double charge. But Rutherford still desired decisive, direct proof"" and here his skilled glassblower came to his aid. Otto Baumbach in 1908 was able to construct glass tubes thin enough to be transparent to the rapidly moving alpha particles yet capable of containing a gas. Such a tube was filled with emanation and was placed within a larger tube made of thicker glass. In time, alpha particles from the decaying emanation penetrated into and were trapped in the space between inner and outer tubes: and when ROYDS SPARKED THE MATERIAL IN THIS SPACE, THEY SAW THE SPECTRUM OF HELIUM.""

‎First appearance of one of the most influential papers in physics in the 20th Century, describing the discovery of the ATOMIC NUCLEUS, and suggesting that the atom consists of a small central nucleus surrounded by electrons. This view of the atom is the one accepted today, and it replaced the concept of the featureless, indivisible spheres of Democritus, which dominated atomistic thinking for twenty-three centuries. Rutherford's 'nuclear atom' was a few years later by Niels Bohr, combined with the quantum theory of light to form the basis of his famous theory of the hydrogen atom.Hans Geiger (Rutherford's assistant in his work on alpha particles) tells ""One day (Rutherford) came into my room, obviously in the best of moods, and told me that now he knew what the atom looked like and what the strong scatterings signified."" - On 7 March 1911, Rutherford presented his principal results to the Manchester Literary and Philosophical Society. The definitive paper came out in the May issue of ""Philosophical Magazine"" (the paper offered here).""After the first five or sic years of intense activity following the discovery of radioactivity, there was a brief lull untill 1911, when a new series of fundamental discoveries was made. These began with the discoveries of the nucleus and of artificial atomic transmutations by Rutherford. By 1811 it was known that electrons entered into the constitution of atoms, and Barkla had shown that each atom has approximately A/2 electrons (where A is the atomis weight). J.J.Thomson had conceived of a model of an atom according to which the electrons were distributed inside a positively charged sphere. To verify this hypothesis, Rutherford had the idea of bombarding matter using alpha-radiation of radioactive bodies and measuring the angles through which the rays were deflected as they passsed through matter. For the Thomson model of the atom the deflections should rarely be more than 1 or 2 degrees.However, Rutherford's experiments showed that deflections of more than 90 degrees could occur, particularly with heavy nuclei.""(Taton (Edt.)
