A Quantum Theory of the scattering of X-Rays by Light Elements.

Front wrapper missing top right corner and front wrapper washed/polished. Internally fine and clean. Compton's paper: pp. 483-502. Entire issue: Pp: 483-584. � First printing of this milestone paper in quantum physics in which Compton verifies Planck's quantum postulate and found that some of the X-rays had in scattering lenghtened their wavelenght. This phenomena was called the "Compton Effect" in his honour. For this discovery Compton received the Nobel prize in physics in 1927.<br><br>"Compton was able to account for this lenghtening of wavelenght by presuming that a photon of light struch an electron which recoiled subtracting some energy from the photon and therefore increasing its wavelenght. This made it seem that a photon acted as a particle: thus after more than a century the particulate natuer of light as evolved by Newton was revived. What itamounted to was that Compton brought to fruition the view that electromagnetic radiation had both a wave aspect and a particle aspect and that the aspect which was most evident depended on how the radiation was tested. De Broglie was at the same time showing that this held true also for ordinary particles such as electrons."

Courtois found this substance which he suspected to be a new element while burning algae in order to obtain sodium and potassium compounds. Although Courtois discovered the element in 1811 the announcement of it was not made until two years later after he had turned it over to Charles Desorm�s and Nicolas Cl�ment.<br><br>"The first publication on iodine are somewhat confusing. Courtois's research is found in a paper attributed to him the paper offered but actually the work of Cl�ment. was followed by an anonymous article the second paper offered. Gay-Lussac. who repeated and extended Courtios's work was responsible for this paper. Courtois himself published nothing. These two articles were immediately followed by short contributions of Gay-Lussac and Humphry Davy on the new element third and fourth paper offered.

CURIE IRENE et MF. JOLIOT. ANNOUNCING THE DISCOVERY OF ARTIFICIAL RADIOACTIVITY NOBEL PRIZE PAPER OF 1935. M. F.
Un nouveau type de radioactivit�. S�ance du 15 Janvier 1934.
Paris Gauthier-Villars 1934. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des S�ances de L'Academie des Sciences" Tome 198 No 3. Titlepage to vol. 198. Pp. 213- 292. Entire issue offered. The joint paper: pp. 254-256 a. 1 photographic illustration in the text. Titlepage with a stamp on verso 2 small tears and a tiny bit of upper right corner gone. Titlepage a bit browned. � First appearance of this seminal paper in which artificial radioactivity was announced for the first time. Curie and Joliot were awarded the Nobel Prize in Chemistry 1935 "in recognition of their synthesis of new radioactive elements".<br><br>"Until this date 1934 atomic nuclei emitting radiation were found in nature: it was called the natural radioactivity. It had been known since Rutherford that this natural radioactivity changed a nucleus into an other one: for instance radium becomes finally lead after many radioactive decays. We could say that lead does not become gold but gold becomes lead! But. this change of matter was not under control. It was not possible to construct the desired chemical element as the alchemist dreamed. But Irene and Frederic Joliot-Curie made the dream become almost reality."<br><br>"Another very important development in the early 1934 by the Joliot-Curies in connection with irradiation of aluminum by alpha particles. The two French scientists detected the production of the recently discovered positrons. . However they soon realized that the positron activity continued after the alpha source was removed and that they had in fact discovered positive beta radioactivity. The importance of the discovery of artificial radioactivity was immediately recognized and resulted in a Nobel Prize in chemistry to the Joliot-Curies in 1935. The new phenomenon immediately became widely employed in nuclear physics chemistry biology and medicine." Kragh Quantum Generations p. 187<br><br>"These elegant experiments which provided the first chemical proof of induced transmutations and showed the possibility of artificially creating radioisotopes of known stable elements were repeated and extended in the major nuclear physics laboratories of various countries " DSB.<br><br>Born on 12 September 1897 in Paris Ir�ne Curie was the daughter of Pierre and Marie Curie. "During World War I she worked as a nurse helping her mother operate radiography equipment and then studied physics and mathematics at the Sorbonne gaining a doctorate for studying the range of alpha particles. She then went to work for her mother at the Radium Institute. There she met Fr�d�ric Joliot whom she married in 1926. Fr�d�ric Joliot was born on 19 March 1900 in Paris - He joined the Radium Institute in 1925 and obtained his PhD in 1930. Together the Joliot-Curies worked on radioactivity and the transmutation of the elements. Twice they just missed major discoveries: in 1932 when Chadwick beat them to the neutron and in 1933 when Anderson discovered the positron. However in 1934 whilst bombarding light elements with alpha particles the Joliot-Curies noticed that although proton production stopped when the alpha particle bombardment stopped another form of radiation continued. The alpha particles had produced an isotope of phosphorus not found in nature. This isotope was radioactive and was decaying through beta-decay" DSB. unknown
