Experimentally well-constrained masses of 27P and 27S: Implications for studies of explosive binary systems

Abstract

The mass of 27 P is expected to impact the X-ray burst (XRB) model predictions of burst light curves and the composition of the burst ashes, but large uncertainties and inconsistencies still exist in the reported 27 P masses. We have used the -decay spectroscopy of 27 S to determine the most precise mass excess of
