Investigating the Effect of Temperature and Pairing Gaps on Electron Capture Cross-Sections in Neutron-Rich N = 50 Nuclei

We investigated the impact of pairing gaps on β -decay properties of neutron rich nuclei with neutron magic number (N = 50). The Gamow-Teller (GT) strength distributions, nuclear partition functions (NPFs) and electron capture cross-sections (ECCs) were analyzed for 78Ni, 82Ge, 86Kr, and 88Sr by utilizing the deformed proton-neutron quasiparticle random phase approximation (pn-QRPA) model with three different pairing gap schemes. The results show that a change in pairing gaps between like nucleons affects the GT strengths, NPFs and ECCs. The total GT strength, NPF and ECC changed as much as 62
