Abstract
We present a method of evaluating the internal energies in coexisting phases at a thermally driven phase transition by extrapolating finite- lattice Monte Carlo results for cumulants of the energy distributions. The method is demonstrated by determining accurately the internal ene rgies of a two-dimensional Ising model with multiple-spin interactions in the horizontal direction and two-body interactions in the vertical direction.
