Comparison of Gamow-Teller strengths in the random phase approximation

Abstract

The Gamow-Teller response is astrophysically important for a number of nuclides, particularly around iron. The random phase approximation (RPA) is an efficient way to generate strength distributions. In order to better understand both theoretical systematics and uncertainties, we compare the Gamow-Teller strength distributions for a suite of nuclides and for a suite of interactions, including semi-realistic interactions in the 1p1p-0f0f space with the RPA and a separable multi-shell interaction in the quasi-particle RPA. We also compare with experimental results for GT_- on 54{54}Fe.
