摘要：

Transverse spin dynamics have been measured for a very dilute -43He mixture (x3=1.82×10-3) polarized by an 8-T magnetic field. The sample was confined to a small spherical resonator, resulting in well-defined spin-wave modes for temperatures below 50 mK. Results are presented for the spin-rotation parameter int and spin-wave dispersion D/int. It is found that int increases monotonically as the temperature is decreased below the degeneracy temperature TF, in apparent disagreement with an earlier experiment. © 1990 The American Physical Society.
