The formula for the temperature dependence of the effective mass of a 4He atom in the superfluid and normal phases is obtained. This expression for the effective mass allows one to eliminate infra-red divergences, being applicable at all temperatures, except for a narrow fluctuation region 0.97 ≤ T/...
