摘要：

We report results of a path integral Monte Carlo simulation of a liquid 3He- 4He mixture at low temperature. In the limit of low 3He concentration, a kinetic energy of 17 K is found for the 3He atoms; the 3He effective mass is m*=2.3m. The restricted path integral Monte Carlo method was utilized to investigate the separation of the mixture into a 3He- and 4He-rich phase. © 1995 The American Physical Society.
