Erste Ausgabe. - "The last part of Stern's program had a completely different outcome. Dirac had promulgated a theory according to which the ration of the magnetic moment of the proton to that of the electron should have been the same as the inverse ration of their masses. This theory was believed so generally that when Stern, O. R. Frisch, and this writer began the very difficult experiments, they were told more than once by eminent theoreticians that they were wasting their time and effort. But Stern's perseverance paid off. Measurements showed a proton magnetic moment two or three times larger than expected. While that result has since been reproduced with greater accuracy, a really satisfactory theoretical explanation is still outstanding. It is this work that was specifically mentioned in Stern's Nobel Prize citation" (DSB). - Einband leicht gebräunt und sauber restauriert. Wohlerhalten. - DSB 13, 40
