Determination of $$\alpha $$-optical potential for reactions with p-nuclei from the study of ($$\alpha $$,n) reactions in the astrophysically relevant energy region

Optical potential parameters in nuclear model calculations are determined by fitting elastic scattering angular distribution data. Due to the dominance of Coulomb part, is performed at much higher energies. As a result, change required for low-energy astrophysical reactions. A different approach suggested using ( $$\alpha $$ ,n) reaction determine modified alpha optical potentials suitable astrophysically relevant low energy regions. Reactions on p-nuclei mass region $$\approx 92–168 have been chosen and McFadden–Satchler -optical obtained from The effect level density $$\gamma -ray strength function also studied this new analyzing ,\gamma ) cross-sections.
