摘要
A microscopic calculation of the effective mass of one He impurity in homogeneous liquid He at zero temperature is performed for an extended Jastrow--Slater wave function, including two-- and three--body dynamical correlations and also backflow correlations between the He atom and the particles in the medium. The effective mass at saturation density, , is in very good agreement with the recent experimental determination by Edwards {\it et al}. The three-- particle correlations appear to give a small contribution to the effective mass and different approximations for the three--particle distribution function give almost identical results for .
