About this Item

8vo, xii, 248 pp., numerous figures and tables, 8 b/w plates. Original blue cloth, gilt lettering to spine. Cover a little soiled at edges through handling, spine darkened. Internally clean and fresh. Ownership signature of Emilio Segrč with date 1934 on title-page and his revisions on pp. 236--239. First edition with this title, this is essentially the third and much expanded edition of Aston's classic book "Isotopes". Segrč clearly used the book in his researches, and revised and expanded in manuscript Aston's 'Table of Isotopes and their Abundance' and his 'Periodic Table of the Elements' on pp. 236--239. There are also pencil markings on the title-page and preface that suggest this copy might have been used in the preparation of a new edition. Francis William ASTON (1877--1945) was a prominent British chemist and physicist who made significant contributions to the field of mass spectrometry. He worked at the Cavendish Laboratory in Cambridge under J.J. Thomson, where he devised a mass spectrograph that allowed for precise measurements of atomic masses. Using this instrument, he made groundbreaking discoveries in the field of isotopes, leading to his formulation of the 'whole-number rule', which states that the masses of the isotopes are whole number multiples of the mass of the hydrogen atom. Aston was awarded the Nobel Prize in Chemistry in 1922. Emilio SEGRČ (1905--1989) discovered technetium, the first artificially synthesized chemical element that does not occur in nature. He was also a member of the team that discovered astatine, the rarest naturally occurring element, and plutonium-239, later used in the bomb dropped on Nagasaki. Segrč, together with a colleague at the University of California, Berkeley, shared the 1959 Nobel Prize in Physics for their discovery of the 'antiproton', a particle with the same mass and spin as the proton but with opposite charge and magnetic moment.
