Nuclear Magnetic Relaxation of Liquid 3He in a Constrained Geometry
We have measured the nuclear magnetic relaxation properties of liquid 3He contained within a vessel filled with fine carbon powder. The purpose of the experiments was to gain a better understanding of the surface relaxation mechanisms for 3He atoms at low temperatures in order to: (1) interpret the NMR relaxation rates in thin films, and (2) look for more general manifestations of the apparent magnetic thermal coupling between 3He and paramagnetic salts observed at low temperatures.1
