Investigation of the cross sections for (α, γ) reactions for p-nuclei 90Zr, 121Sb, 151Eu, and 162Er was conducted by varying different α- Optical Model Potentials (OMPs) for a set of Level Density Model (LDM) and Radiative Strength Function (RSF). The calculations were performed within the framework of TALYS-1.96 code, with the primary inputs being the
OMP, the LDM, and the RSF. We have fine-tuned the input models of TALYS-1.96 to regenerate the experimental data of cross sections. The present investigation was analyzed based on the root mean square error (rms). Good agreement was achieved for all nuclei under study using various model combinations. Based on the radiative capture cross sections, we have computed the rates which can be used as inputs to various astrophysical models.
