抄録

The higher order correction term is obtained for the Monte Carlo calculation of the path integral, The correction is expressed only by a modification of the potential term: V(r1,.,rN)®+V+(h+2/24m)(B/M)2 ENi=1(dV/dri)2, where ri's are coordinates of particles, N is number of particles with mass m, B is (kT)-l and M is number of partitions. By this method one can reduce the computation time remarkably. A rapid convergence of energy is obtained for the case of harmonic oscillator.
