Abstract

The spin-lattice relaxation time T1 and the coefficient of self-diffusion D were measured in liquid He3 in the temperature range between 0.35 and 3°K at SVP. Pulsed nuclear magnetic resonance in a field of 6800 G was used. The measured T1, characteristic of bulk relaxation, was found to pass through a minimum value of about 290 sec in the vicinity of 1°K. Surface relaxation effects were examined and possible explanations for the great diversity of the T1 values reported in the literature are given. Certain details of experimental procedure are described.
