Irène Curie / Pavel Savitch, - Sur les radioéléments formés dans l'uranium irradié par les neutrons I & II. In: Journal de Physique - 1937-1938

On the radioelements formed in uranium irradiated by neutrons I & II. In: Journal de Physique et le Radium + Bibliographic Review and Proceedings, vol. 8, no. 10, pp. 385-387 & vol. 9, no. 9, pp. 355-359, October 1937 & September 1938.
Joliot-Curie, Irène & Savic, Pavel
First edition, complete issues of the journal in their original printed covers, dedicated to one of Irène Curie's missed opportunities, during which she and her student Savic observed, but could not accept, the process of nuclear fission. It was during the years leading up to World War II that Irène Joliot-Curie carried out her most remarkable individual work. With her extensive experience in radiochemistry, she sought to analyze the complex phenomena resulting from the bombardment of uranium by neutrons.
Very good specimens in very good condition and coming from a library declassification.
