摘要：
We present a dynamical calculation of electron screening for d-D nuclear reactions, in the energy range relevant for star interior and fusion reactors, in the framework of the classical trajectory Monte Carlo method. It is shown that the numerical results, in the limit of low and high velocity, agree with the quantum mechanical values derived within the adiabatic and sudden approximation respectively. Corrections to the bare nucleus cross sections in excess of 10% are found for c.m. energies below 1 keV. As a check of the calculation method, we also evaluate the large-angle electron transfer probability. © 1990.
