Understanding the mirror asymmetry in Gamow-Teller transition rates between Al()Si and P()Si
L. Xayavong, N. A. Smirnova, Y. Lim
The long-standing discrepancy between shell-model and experimental values of the mirror asymmetry in Gamow-Teller transition rates for Al()Si and P(…

Constraining theoretical Corrections to Gamow-Teller Transition Rates
L. Xayavong, Y. Lim
We propose two novel constraints for the theoretical corrections to Gamow-Teller transition rates. The first, derived from a two-level model, predicts forbidden regions within the…

Shell-model calculation of isospin-symmetry breaking correction to superallowed Fermi beta-decay
L. Xayavong, N. A. Smirnova, M. Bender +1
We investigate the radial-overlap part of the isospin-symmetry breaking correction to superallowed -decay using the shell-model approach similar to that of Refs. [1, 2]…
