Microscopic study of $\left(p,\gamma \right)$ reactions in the mass region $A=110-125$

Low-energy proton capture reactions have been studied in a statistical model using the semimicroscopic optical potential in the mass range $A=110-125$. Nuclear density obtained from relativistic mean-field calculations has been folded with nucleon-nucleon interactions to obtain the optical potential. Theoretical results have been compared with experimental measurements to normalize the potential. Results have also been compared with a standard calculation available in the literature.
