摘要：

The nuclear magnetic susceptibility of submonolayer He3 films adsorbed on a graphite substrate has been measured for temperatures between 6 and 800 mK. Three distinct surface-density regimes are identified for fractional monolayer coverages below perfect registry. These appear to be a fluid phase with some atoms localized by substrate heterogeneity, a solid-fluid coexistence region, and a registered solid phase with defects. T2 values inferred from NMR linewidth measurements are also reported. © 1990 The American Physical Society.
