摘要：
We present a method using a basis set to calculate the optimized Jastrow pair function in trial wave functions for quantum fluids and solids. Using three-body terms in the variational trial wave function, as well, the variational Monte Carlo binding energies obtained are significantly lower than determined previously. The radial distribution functions g(r) with these Jastrow functions are presented and discussed.
