Abstract
ATOMIC BEAM SOURCE OF POLARIZED ELECTRONS: (1) Large depolarization effect in potassium beam experiments: Non-adiabatic transitions and collisions with gas molecules were proven not responsible for polarization observed after elimination of potassium molecules. The following effects were responsible: insufficient energy discrimination in the Mott scattering apparatus and the overlap by the strong line of the high-pressure mercury arc on the wavelength of the second resonance transition in potassium. (2) Higher intensity source of polarized electrons: a pulsed light source and a lithium atomic beam were selected for improving the source of polarized electrons. (3) A high-pressure-spark light source was built as a source of polarized electrons. MAGNETIC RESONANCE: Precision measurement was made of the ratio of the nuclear magnetic moment of He-3 to that of the proton (W. C. Williams and V. W. Hughes, Bull. Am. Phys. Soc., 11:121 (1966)).
