Abstract
Results are reported for high frequency pulsed NMR studies of He-3 adsorbed on hexagonal boron nitride. The commensurate coverage, corresponding to a 0.75 fraction of a monolayer was studies. The temperature dependence of the nuclear spin-spin relaxation time was measured in the range of 0.1-2 K. Fr om the relaxation times, the quantum mechanical exchange rates are calculat ed for a triangular array of He-3 atoms.
