Offprint. Originnal Wrappers. Includes Errata slip with 7 corrections. Very good. "[In 1948] Kroll and Lamb and, right thereafter, French and Weisskopf submitted their papers on the Lamb shift. Deftly these authors had managed to obtain correct answers by non-covariant methods. . . With the successful completion of the magnetic…momemnt and Lamb shift calculations, a solid beachhead had been established in uncharted terrain, the physics of radiative corrections" :: Abraham Pais, Inward Bound, pp.460-461. This paper represents a significant step in the research which would, 6 years later, result in Lamb winning the Nobel Prize in Physics. Willis E. Lamb was an American physicist who won the Nobel Prize in Physics in 1955 for research related to his discovery of the Lamb Shift. Norman M. Kroll was an American theoretical physicist known for his pioneering research in Quantum Electrodynamics, at the Institute for Advanced Study, went on to become a professor of physics at Columbia and later head of the physics department at UCSD.

Lamb attended the University of California at Berkeley for both his undergraduate and post-graduate studies. "For theoretical work on scattering of neutrons by a crystal, guided by J. Robert Oppenheimer, he received the Ph.D. in physics in 1938. Because of limited computational methods available at the time, this research narrowly missed revealing the Mossbauer Effect, 19 years before its recognition by Mossbauer" (Wikip.). "A Note on the Capture of Slow Neutrons. . . ," presented on November 9, 1936 and published in Physical Review in 1937, contributed to the first part of Lamb's thesis dissertation. The title of the dissertation was "I. On the capture of slow neutrons in hydrogenous substances. II. Electromagnetic properties of nuclear systems." "At Ann Arbor, I had heard Fermi lecture on the effect of chemical binding of a hydrogen atom on its scattering of slow neutrons. This interested me, and I began to work on related problems. It seemed that there might also be an effect of the binding of a hydrogen atom on the capture cross section for slow neutrons. At first I thought the effect would be large, but finally had to settle for a very rough estimate of the cross section for a very unlikely process: the radiationless capture of neutrons by bound protons to form deuterons, with the excess energy and momentum going into vibrational motion of the deuteron instead of a gamma ray. The normal capture process was very little affected by the chemical binding. Even today, this radiationless capture has never been seen, but I am still hoping that someday it may be. This work formed part of my doctoral thesis. The other part dealt with electromagnetic properties of nuclear matter" (Lamb, p. 136). "There is no greater tribute to Oppenheimer than the list of Ph.D.s he delivered, which includes Carlson, Christy, Dancoff, Kusaka, Lamb, Morrison, Snyder, and Volkoff" (Pais, p. 369). "Lamb was an American physicist who received the Nobel Prize for Physics in 1955 for his precision measurements of details of the spectrum of hydrogen. These included studies of fine structure and measurements of the Lamb shift, a key observational step on the road to the development of the theory of quantum electrodynamics (p. 203). Gribbin, John.

"Early theoretical efforts on heavy-ion stopping date back to Bohr (1940) who pointed out the importance of screening due to projectile electrons in the slowing-down of fission fragments, and to Lamb (1940) and Knipp and Teller (1941) who studied the problem of charge equilibrium for penetrating heavy particles" (Sigmund, p. 19). Niels Bohr (1885-1962), the renowned Danish quantum and nuclear physicist, had been working in Copenhagen on determining how fission fragments penetrate matter simultaneously with Lamb's experiments. In a letter that he wrote to Tom Lauritsen, a contemporary physicist, Bohr mentions this article specifically, writing: "Just a few days ago I received a copy of Physical Review of October 15 which, as you may have seen, contains a paper of Lamb, who has independently achieved many of the results arrived at in Copenhagen. I thought, therefore, that it might be best to my last paper in the Physical Review to add a small addendum like that enclosed and I should be glad if you will kindly see that it is introduced in the proof. . . . In Lamb's article I also found various references to experimental investigations of fission fragments which we have overlooked or not yet known in Copenhagen" (Bohr et al., p. 239). At the conclusion of Bohr's paper, "Velocity-Range Relation for Fission Fragments," he writes, "Note added at proof.â"After the present paper was sent from Copenhagen, we received here the issue of The Physical Review of October 15, 1940, which contains an article by W. E. Lamb on the passage of uranium fission fragments through matter. In main features the considerations of this article correspond to the arguments developed here and similar results are obtained" (Bohr, p. 275). Bohr, Niels.
