Abstract:

New measurements of the nuclear susceptibility of liquid helium-3 between 0.045 and 1.3 K and up to 30.7 atm will be described. At the lowest temperatures, the susceptibility for all pressures has almost reached a constant value. The effective Fermi temperature TF from these measurements is found to vary from 0.43K at 0.5 atm to about 0.26K at 30.7 atm. From these measurements and recent specific-heat data of several authors, the spin-dependent exchange constant is calculated and is found to decrease with increasing pressure and density. The spin specific heat calculated from susceptibility according to Goldsteins theory is compared to available data. The susceptibility results are compared to recent data of Anderson, Reese, and Wheatley. Author
