Analysis of (p,γ) capture cross-sections relevant to <i>p</i> -process using TALYS for <i>A</i> = 75–110
The proton capture ([Formula: see text]) cross-sections for eight different atomic nuclei in the mass region [Formula: see text]–110 were calculated within the nuclear reaction model code TALYS. For all the reactions, we tested different combinations of inputs for level density (l.d) parameter and gamma strength function ([Formula: see text]). Finally, it was observed that the application of hybrid input in TALYS (macroscopic l.d and microscopic or semi-microscopic [Formula: see text] or in abbreviation mac-mic) resulted in successful agreement of theoretical prediction that the existing experimental data. Isospin correction was also incorporated in a few cases which improved the matching if the center-of-mass energy reached the threshold energy of the opening of ([Formula: see text]) channel. The corresponding thermonuclear reaction rates were calculated for all the nuclei and some discrepancies were found with the prediction of the NONSMOKER code. Using the particular mac-mic input combination, the cross-section and reaction rate for the nuclei [Formula: see text]Nb and [Formula: see text]Mo were calculated within TALYS. These two nuclei lack experimental data but are highly important for understanding early solar system processes. This is a rare attempt to explain the p-capture cross-section of different p-nuclei ([Formula: see text]–110 range) with similar set of input combinations in TALYS, which may help to remove the uncertainty generated due to the variation of input parameters within nuclear statistical model codes.
