Exposés de Physique atomique expérimentale

Abstract

THE author's own researches in the field covered by this volume enable him to discuss with both brevity and thoroughness the technique and results of the new spectrometry and to show their bearing on such questions as the energy and stability of the nucleus. The first part treats of the masses and the methods and instruments used in measuring them, from that of Aston of 1927 to the double-focusing ones of the present day. The second deals with isotopes, including those of artificial radioactive substances, their detection and measurement, and the third with the principal numerical relations, such as that of the mass to the charge of the nucleus, and the even and odd law, which have been discovered among the 260 isotopes at present known. The volume is well supplied with plates, figures, numerical tables of results, and a bibliography brought well down into 1937.
