Abstract

We study Gamow–Teller strength distributions in some selected nuclei of particular astrophysical interest within the iron mass region. The theoretical framework is based on a proton–neutron quasiparticle random phase approximation built on a deformed selfconsistent mean field basis obtained from two-body density-dependent Skyrme forces. We compare our results to available experimental information obtained from (n,p) and (p,n) charge exchange reactions.

Self-consistent calculations of electron-capture decays in Z=118, 119, and 120 superheavy isotopes
2021, Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Weak decays in superheavy nuclei with proton numbers $Z = 118 - 120$ and neutron numbers $N = 175 - 184$ are studied within a microscopic formalism based on deformed self-consistent Skyrme Hartree-Fock mean-field calculations with pairing correlations. The half-lives of $β^{+}$ decay and electron capture are compared with α-decay half-lives obtained from phenomenological formulas. The sensitivity of the half-lives to the unknown Q-energies is studied by comparing the results obtained from different approaches for the masses. It is shown that α-decay is always dominant in this mass region. The competition between α and $β^{+} / E C$ decay modes is studied in seven α-decay chains starting at different isotopes of Z=118, 119, and 120.
Investigation of Gamow Teller transition properties in <sup>56–64</sup>Ni isotopes using QRPA methods
2018, Nuclear Physics A
Weak rates in nickel isotopes play an integral role in the dynamics of supernovae. Electron capture and β-decay of nickel isotopes, dictated by Gamow–Teller transitions, significantly alter the lepton fraction of the stellar matter. In this paper we calculate Gamow–Teller (GT) transitions for isotopes of nickel, ${}^{56 – 64}{Ni}$ , using QRPA methods. The GT strength distributions were calculated using four different QRPA models. Our results are also compared with previous theoretical calculations and measured strength distributions wherever available. Our investigation concluded that amongst all RPA models, the pn-QRPA(C) model best described the measured GT distributions (including total GT strength and centroid placement). It is hoped that the current investigation of GT properties would prove handy and may lead to a better understanding of the presupernova evolution of massive stars.
