Abstract

Effect of the tensor force on β\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^{34}Si, 68^{68}, 78^{78}Ni and 132^{132}Sn. The tensor correlation induces strong impact on low-lying Gamow-Teller state. In particular, it improves the ?β\beta-decay half-lives. QQ and ftft values are also investigated and compared with experimental data.
