    Nuclear susceptibility of helium three liquid and gas
    (1964) Manka, Robert Hall; Rorschach, Harold E., Jr.
    The technique of adiabatic fast passage has been used to measure the relative magnetic susceptibility, X , of He3 and mixtures of He3-He4 with an experimental r.m.s. deviation of ±1%. Two types of measurements were made: (1) Measurement of X versus temperature (from 1.96°X to 0.93°K) of pure He3 liquid, and He3-He4 mixtures containing 35%, 14%, and 5% He3. (2) Measurement of relative X versus density of pure He3 gas at 2.99°K, with density varying from 1.1 x 10-3 to 4.5 x 10-3 moles/cc. Preliminary measurements of X versus density, p , of He3 atoms, for 2 x 10-3
