Özet
Gamow-Teller (GT) transitions play a fundamental role in exploring nuclear structure and weak-interaction-mediated decay modes. In this study, a detailed investigation of the GT strength distributions for the neutron-deficient nucleus 74Kr is presented. The theoretical framework is porating both particle-hole (ph) and particle-particle (pp) residual interactions. To examine the influence of different interactions, comparative analyses are performed using a schematic model and the Pyatov method. The resulting GT strength distributions are systematically compared with available experimental data to evaluate the predictive capacity of the employed models. This work contributes to a deeper understanding of spin-isospin excitations in nuclei near the N approximate to Z line and provides valuable insights for future studies on weak-interaction processes in exotic nuclei.
