New shell-model calculations of the $δ_{C}$ correction to superallowed $0^{+} \to 0^{+}$ nuclear $β$ decay and standard-model implications

L. Xayavong, N. A. Smirnova, F. Nowacki

Refined calculations of the radial mismatch correction, $δ_{C 2}$ , to superallowed $0^{+} \to 0^{+}$ nuclear $β$ decay are performed using the shell model with realistic Woods-Sax…

Radial excitations and their potential impact on Fermi $β$ -decay rates

L. Xayavong, Y. Lim, N. A. Smirnova +1

We investigate the contribution of radial excitations to Fermi $β$ -decay matrix element. To this end, exact no-core shell model calculations are performed for the mirror $β$ decay…

Refining the isovector component of the Woods-Saxon potential

L. Xayavong, Y. Lim, N. A. Smirnova +1

We investigate the isovector component in the phenomenological mean field model of nuclei. Lane's isospin dependence, initially proposed for the nuclear optical potential, is reexa…
