Abstract
Solidification and melting of dilute He-3-He-4 mixtures (0.7%-4.0% He- 3) at 0.45K - 1.2K are investigated, utilizing a 10 MHz NMR imaging sy stem. The spatial distribution of He-3, T1 and T2 relaxation times was mapped along the vertical direction of the experimental cell, perpend icular to the liquid - solid interface. We find that relaxation on the melting curve is considerably faster than at higher densities.
