On the asymmetry of Gamow–Teller β-decay rates in mirror nuclei in relation with second-class currents
The theoretical evaluation of major nuclear structure effects on the asymmetry of allowed Gamow–Teller β-decay rates in light mirror nuclei is presented. The calculations are performed within the shell model, using empirical isospin-nonconserving interaction and realistic Woods–Saxon radial wave fun...

Summary: | The theoretical evaluation of major nuclear structure effects on the asymmetry of allowed Gamow–Teller
β-decay rates in light mirror nuclei is presented. The calculations are performed within the shell model, using empirical isospin-nonconserving interaction and realistic Woods–Saxon radial wave functions. The revised treatment of
p-shell nuclei is supplemented by systematic calculations for
sd-shell nuclei and compared to experimental asymmetries when available. The results are important in connection with the possible existence of second-class currents in the weak interaction. |
