Lancaster: American Physical Society, 1939. 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. Item #389
