Impact of tensor force on β-decay of magic and semi-magic nuclei

Abstract

Effect of the tensor force on $\beta$?-decay is studied in the framework of the proton-neutron random-phase-approximation (RPA) with the Skyrme force. The investigation is performed for even-even semi-magic and magic nuclei, ${}^{34}$Si, ${}^{68}$, ${}^{78}$Ni and ${}^{132}$Sn. The tensor correlation induces strong impact on low-lying Gamow-Teller state. In particular, it improves the ?$\beta$-decay half-lives. $Q$ and $ft$ values are also investigated and compared with experimental data.
