Impact of Nuclear Deformation on GT Strength Distributions in Iron Isotopes within QRPA-Based Approaches

Abstract

Gamow-Teller (GT) transitions play a crucial role in nuclear structure studies and astrophysical modeling by providing insights into spin-isospin excitations. In this work, GT strength distributions—both B(GT)- and B(GT)+—are systematically calculated for selected iron isotopes within the proton-neutron Quasiparticle Random Phase Approximation (pn-QRPA) framework. The analysis incorporates both particle-hole and particle-particle channels and includes complementary approaches based on the schematic model and the Pyatov method. To assess the impact of nuclear shape, calculations are performed using different quadrupole deformation parameters derived from experimental and theoretical sources. The results demonstrate the sensitivity of GT strength to nuclear deformation and model choice. Comparisons with experimental data highlight the reliability of the deformed QRPA-based models, offering valuable input for astrophysical applications involving weak interaction processes.
