Many-body approach to proton emission and spectroscopic factors
Abstract
A formal study of the proton emission process is presented. The decay width for the process is re-derived in a time-dependent formalism that makes use of the two-potential approach by Gurvitz and Kalbermann and places special emphasis on the proper treatment of many-body effects. We demonstrate that the many-body aspects of the problem are contained in an overall normalization factor for the decay width. While this result agrees with traditional approaches to proton emission, we find that the usual interpretation of the normalization as the square root of a spectroscopic factor is not necessarily correct. This result has important consequences for extracting spectroscopic factors from proton emission experiments. (This work was performed in part under the auspices of the U. S.
