The nuclear ground state properties and shape parameters were calculated using the Relativistic Mean Field model. Three different density-dependent interactions ((DC)-C-3, DD-ME2 and DD-PC1) were used in the calculation. Estimated shape parameters were later used within the framework of deformed proton-neutron quasi-random phase approximations model, with a separable interaction, to calculate the GT strength distributions, half-lives and branching ratios for these neutron-deficient isotopes. It was concluded that half-lives and GT strength distributions vary considerably with change in shape parameter.eninfo:eu-repo/semantics/closedAccessGamow-Teller strength; deformed p-n-QRPA model; RMF model; nuclear structure; nuclear deformationArticle98810.1088/1402-4896/ace80b2-s2.0-85166481711Q1WOS:001037379500001Q2
