Abstract
A pulsed 10 MHz NMR system for imaging He-3 - He-4 mixtures on the mel ting curve between 0.4K to 1.5K is described. The spatial distribution of He-3, T1 and T2 relaxation times were mapped along the vertical di rection, perpendicular to the liquid-solid interface. Multi-exponentia l fits for the relaxation times were made. These are useful to follow the relaxation of structural inhomogeneities in the crystal.
