An efficient technique for maintaining large {sup 3}He nuclear spin polarizations in liquid {sup 3}He-{sup 4}He mixtures has been developed and used to polarize samples contained in narrow tubes. Results obtained in a U-shaped cell and a coil-shaped cell are compared. A systematic study of the effects of dipolar fields within the sample on the characteristics of the observed long-lived magnetostatic modes is in progress. NMR signals obtained in the coil-shaped cell reveal phase separation and the existence of a highly polarized {sup 3}He-rich region in the sample.
