A microscopic calculation of the effective mass of one [sup 4]He impurity in homogeneous liquid [sup 3]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 [sup 4]He atom and the particles in the medium. The effective mass at equilibrium density, [ital m][l angle][ital main][r angle][sub 4][sup *]/[ital m][sub 4]=1.21, is in very good agreement with the recent experimental determination by Edwards [ital et] [ital 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 [ital m][sub 4][sup *]/[ital m][sub 4].
