Neutron physics: A revision of I. Halpern's notes on E. Fermi's lectures in 1945. Goudsmit's copy

[Fermi, Enrico (1901-54).] Beckerley, James G. (1915-2006). Neutron physics: A revision of I. Halpern's notes on E. Fermi's lectures in 1945. ii, 96pp. Text illustrations. 267 x 201 mm. Oak Ridge, TN: United States Atomic Energy Commission, Technical Information Branch, n.d. [1949]. Original printed wrappers, stapled, light soiling, front wrapper chipped, spine partially defective. Very good. From the library of Samuel Goudsmit (1902-78), with his stamp and name in pencil on the front wrapper; bookplate of the American Institute of Physics's Niels Bohr Library stating that this is Goudsmit's copy. First Edition. "In the Fall of 1945 a course on Neutron Physics was given by Professor Fermi as part of the program of the Los Alamos University . . . The present revision is based on class notes prepared by I. Halpern with some assistance by B. T. Feld and issued first as document LADC 255 and later with wider circulation as MDDC 320. Having found the document most useful in teaching an introductory course in nuclear physics, the author of the present revision felt that the material should be made more widely available . . . To this end the notes issued as MDDC 320 have been revised and made available in this form for wiser distribution" (p. i). Beckerley, an American nuclear physicist, was the director of classification at the U.S. Atomic Energy Commission. This copy is from the library of Samuel Goudsmit, co-discoverer of electron spin. .…
