The Gamow -Teller (GT) strength distributions of sd-shell N = Z nuclei (24Mg, 28Si, and 32S) are investigated within the framework of proton-neutron quasi -particle random phase approximation (pn-QRPA) using a deformed basis. The nuclear properties of these special nuclei were investigated by the Relativistic Mean Field (RMF) model. The RMF framework with density -dependent interactions (DD-PC1 and DD-ME2) was employed to compute ground -state deformation parameters (/32) using potential energy curves. The /32 values computed from the RMF and the finite range droplet model (FRDM) were employed as a free parameter in the pnQRPA calculation to investigate the resulting GT strength distributions. The present model -based analyses compare well with the observed data.
