Two-phonon structures for beta-decay theory

Year: 2018
Type: conference-paper
Abstract: The β-decay rates of 60 Ca have been studied within a microscopic model, which is based on the Skyrme interaction T45 to construct single-particle and phonon spaces. We observe a redistribution of the Gamow–Teller strength due to the phonon-phonon coupling, considered in the model. For 60 Sc, the spin-parity of the ground state is found to be 1+. We predict that the half-life of 60 Ca is 0.3 ms, while the total probability of the βxn emission is 6:1%. Additionally, the random matrix theory has been applied to analyze the statistical properties of the 1 + spectrum populated in the β-decay to elucidate the obtained results.
