Gamow-teller strength and electron capture cross-section calculation by pn-QRPA for selected fp-shell nuclei

Abstract

The
allowed Gamow-Teller (GT) strengths and associated weak interaction rates on
fp-shell nuclides are the most familiar processes of spin-isospin (στ) type. These
rates play a crucial role in several astrophysical processes, particularly in
nuclear synthesis and supernova-explosions. As per simulation consequences, the
electron capture cross-section on medium-heavy nuclei has a key impact on
decreasing the ratio of electron-to-baryon of the stellar matter during the
late stages of stars formation. Stellar model based on the theoretical
approaches should be tested against the available measured data. In the current
work we present calculated Gamow-Teller strength distributions by pn-QRPA model
for selected fp-shell nuclei (
42Ti, 46Cr, 50Fe
and
54Ni) and compare our results with available measured data. The
Gamow-Teller strength distributions are well fragmented over the energy range
0-12 MeV and have a good comparison with experimental data. We calculate the electron
capture cross-section for selected nuclei at temperature 0.5 MeV, 1.0 MeV and
1.5 MeV that shows the temperature dependence of calculated electron capture cross-section for astrophysical applications.
