Phys. Rev. Lett. 80, 4709–4712 (1998)Concentration Dependence of the Effective Mass of 3He Atoms in 3He-4He MixturesReceived 8 October 1997; published in the issue dated 25 May 1998 Recent measurements by Yorozu et al. [S. Yorozu, H. Fukuyama, and H. Ishimoto, Phys. Rev. B 48, 9660 (1993)] as well as by Simons and Mueller [R. Simons and R. M. Mueller, Czech. J. Phys. Suppl. 46, 201 (1996)] have determined the effective mass of 3He atoms in a 3He-4He mixture with great accuracy. We here report theoretical calculations for the dependence of that effective mass on the 3He concentration. Using correlated basis function perturbation theory to infinite order to compute effective interactions in the appropriate channels, we obtain good agreement between theory and experiment. © 1998 The American Physical Society URL:
