Soft cover. Condizione: Good. Kusch & Foley, "Magnetic Moment of the Electron." American Physical Society, 1948. The Physical Review, 74 (3), Aug 1 1948. __+__Original printed wrappers. This copy is GOOD, only, as there is a dampstain that runs through the issue along the top third or so of the text. It isn't very pronounced, and not evident on the wrappers.but, there it is. I have another better copy for sale in this same medium. Anyway, give the dampstain, the price is much reduced for this copy. __+__ From Kusch's Nobel Prize (1955, physics) speech, "The magnetic moment of the electron Nobel Lecture, December 12, 1955": "I must tell you, and with considerable regret, that I am not a theoretical physicist. A penetrating analysis of the part that the discovery and measurement of the anomalous magnetic moment of the electron has played in the development of certain aspects of contemporary theoretical physics must be left to the group of men who have in recent years devised the theoretical structure of quantum electrodynamics. My role has been that of an experimental physicist who, by observation and measurement of the properties and operation of the physical world, supplies the data that may lead to the formulation of conceptual structures. The consistency of the consequences of a conceptual structure with the data of physical experiment determines the validity of that structure as a description of the physical universe. Our early predecessors observed Nature as she displayed herself to them. As know- ledge of the world increased, however, it was not sufficient to observe only the most apparent aspects of Nature to discover her more subtle properties; rather, it was necessary to interrogate Nature and often to compel Nature, by various devices, to yield an answer as to her functioning. It is precisely the role of the experimental physicist to arrange devices and procedures that will compel Nature to make a quantitative statement of her properties and behav- ior. It is in this spirit that I propose to discuss my participation in a sequence of earlier experiments that made possible the precision determination of the magnetic moment of the electron. I will then discuss the experiments them-selves which have yielded our present knowledge of the magnetic properties of the electron." This issue also contains Maria G. Mayer, "On Closed Shells in Nuclei", which appears in Stoke's "Physical Review, the First Hundred Years".…

[+=]The Nobel Prize in Physics 1944 was awarded to Isidor Isaac Rabi "for his resonance method for recording the magnetic properties of atomic nuclei".--Nobel Foundation. "In 1944 Rabi won the Nobel Prize in Physics for his development of the magnetic resonance method. This method became the basis for nuclear magnetic resonance (NMR), discovered independently by Edward Purcell and Felix Bloch in 1945 and 1946. NMR quickly became an indispensable tool for chemists. Later, Rabi s prize-winning work was the basis for magnetic resonance imaging (MRI), which became an indispensable tool for physicians."--Complete Dictionary of Scientific Biography online.…

Soft cover. Condizione: Near Fine. 1st Edition. First edition, journal issue in original printed wrappers, of the first announcement of the discovery of magnetic resonance. Isidor Isaac Rabi (1898-1988) was awarded the Nobel Prize for Physics in 1944 for developing a "resonance method for recording the magnetic properties of atomic nuclei". His extensive research at Columbia University on investigations into the nature of the force that holds atomic nuclei together led to the creation of the molecular-beam magnetic-resonance detection method. Using this system, physicists were finally able to detect and measure magnetic moments of the nuclei. "The precise measurements yielded by this method made possible such subsequent applications as the atomic clock . . . and the laser, as well as the nuclear magnetic resonance imaging used in diagnostic medicine. Rabi's method provided the central technique for virtually all molecular and atomic beam experimentation" (Encyclopaedia Britannica). Magnetic resonance is not only of central importance in physics, but is also the foundation of magnetic resonance imaging (MRI), which revolutionized medical imaging in the last decades of the twentieth century.

1st Edition. FIRST EDITION IN ORIGINAL WRAPS OF ISIDOR RABI'S INVENTION OF "A MOLECULAR BEAM MAGNETIC RESONANCE METHOD IBY USING TWO MAGNETS IN SUCCESSION TO PRODUCE INHOMOGENEOUS" (Krems, Cold Molecules, p. 510). "The importance of the role that atomic and molecular beams have played in physics and chemistry cannot be overstated. In Rabi's setup, the deflection of particles caused by the first magnet was compensated for by the second magnet such that the particles were directed on a sigmoidal pathe to the detector. A transition to 'other states of space quantization,' induced between the two magnetic sections could be detected via the resulting reduction of the detector signal" (ibid). In 1938 and in another paper, Rabi briefly reported the use of NMR to measure the nuclear magnetic moment; this, the 1939 paper, is the second and more complete report. CONDITION & DETAILS: Lancaster: American Physical Society. Quarto (11.25 x 8.25 inches; 275 x 200mm). Original wraps. Very slight wear at the edges; a bit of fading at the spine.

Soft cover. Condizione: Very Good. 1st Edition. First edition, very rare offprints, of the discovery of magnetic resonance and its application to the measurement of the magnetic moment of the proton and deuteron (and hence of the neutron). Isidor Isaac Rabi (1898-1988) was awarded the Nobel Prize for Physics in 1944 for developing a "resonance method for recording the magnetic properties of atomic nuclei". "The precise measurements yielded by this method made possible such subsequent applications as the atomic clock . . . and the laser, as well as the nuclear magnetic resonance imaging used in diagnostic medicine. Rabi's method provided the central technique for virtually all molecular and atomic beam experimentation" (Encyclopaedia Britannica). Rabi received his doctorate in physics from Columbia University in 1927, and afterwards travelled to Europe to study physics with Bohr, Pauli, Stern and Heisenberg. From Stern, Rabi learned the molecular-beam method, which appealed to him so much that he established his own molecular beam laboratory at Columbia in 1931, shortly after being appointed to the university's physics faculty. Working with some of the best young American physicists of the time, Rabi refined the molecular-beam apparatus and used it to measure the magnetic moment of several lithium compounds [I]. Applying the method to hydrogen, they found that the moment of a proton was 2.785 nuclear magnetons, and not 1 as predicted by the then-current theory, while that of a deuteron was 0.855 nuclear magnetons [II]. Since a deuteron is composed of a proton and a neutron with aligned spins, the neutron's magnetic moment could be inferred by subtracting the proton's magnetic moment from the deuteron's. The resulting value was not zero, and had a sign opposite to that of the proton. This led Rabi to suggested that the deuteron had an electric quadrupole moment [III]. This discovery meant that the physical shape of the deuteron was not symmetric, which provided valuable insight into the nature of the nuclear force binding nucleons. "As Hans Bethe observed, there were three key events in the formative years of nuclear physics, one of them being the discovery of the quadrupole moment of the deuteron. Without Rabi's development of the magnetic resonance method to a state of considerable precision, this discovery would not have been possible" (Magill, The Nobel Prize Winners: Physics, II, p 513).
