On the thermal mass shift of nucleons

of a nucleon in the finite temperature pion gas is calculated in the case of an arbitrary nucleon momentum. A general formula is used which relates the in-medium mass shift

\Delta m(E)

of a particle to the real part of the forward scattering amplitude

Re f(E)

of this particle on constituents of the medium and its applicability domain is formulated. The mass shift of the nucleon in thermal equilibrium with pion gas is also calculated.
