Title: Influence of protons on the capture of electrons by {sup 7}Be in the Sun

Abstract

The capture of electrons by the nucleus {sup 7}Be from the three-body initial state p+e{sup -}+{sup 7}Be in the continuum is studied. On the basis of the expansion of the three-body continuum wave function in the small parameter {epsilon}{approx_equal}(m{sub e}/m{sub p}){sup 1/2} [m{sub e} (m{sub p}) is the electron (proton) mass], the role of the protons on the electron capture is considered. The results are compared with the traditional treatment of the electron capture by the nucleus {sup 7}Be. For stars with density and temperature like in the center of the Sun the studied mechanism can make a non-negligible contribution to the capture rate.
