Abstract

Pycnonuclear triple-α reaction rates are calculated for mass densities from 10⁸ to 5 × 10⁹ g cm ^-3. The plasma is assumed to be a fluid phase of a particles interacting through both nuclear and Coulomb potentials. It is described by Jastrow-type two-body correlations. The many-body wave function is determined variationally within a space of trial two-body wave functions that reproduce the expected long- and short-range behaviors of the correlations. The resulting three-body fusion rates are compared to previous calculations.
