Abstract

We analyse the variance of the Hamiltonian with respect to a Jastrow wave function for extended nuclear matter. Numerical results are presented for a semi-realistic central potential and state independent correlations which are suitably constrained for good cluster convergence.

Jastrow-type calculations for nuclear matter with the normalization condition
1978, Nuclear Physics, Section A
Results are given of constrained Jastrow calculations for the energy per particle and the density of nuclear matter using the test potentials IY and OMY-6, as well as several others, and various correlation functions involving parameters. The constraint chiefly employed is the normalization condition in first order, a condition naturally entering the Jastrow formalism. The energy in the minimization is approximated by the first two and in some cases by the first three terms of its FIY cluster expansion. In addition to the three-body terms in the FIY expansion, the corresponding terms of the AHT expansion are also calculated for comparison. From the computations which were performed it seems that, at least in some cases, the normalization condition constitutes a quite satisfactory constraint, leading to reliable results, when used in low order calculations. In addition, conclusions are drawn as to the sensitivity of the results to the constraint, correlation function and minimized energy expression.
