Lancaster, 1933.
Erste Ausgabe. - "A few months before Rutherford's prediction, Harkins in 1920 predicted the existence of the neutron. But it was not until 1932 that the neutron was actually observed, by James Chadwick at Cambridge. Immediately after Chadwick's discovery, Harkins, with David Gans and other co-workers, began investigations of nuclear reactions involving these particles. Chadwick and Rutherford contended that nuclear reactions initiated by bombardment could occur without capture of the bombarding particle, but Harkins showed evidence (measured energy losses) that in forming an excited nucleus capture always occurs" (DSB). - Einband gering fleckig, sonst gut erhalten. - DSB 6, 117.
