We have suggested semi-empirical formulas including the non-elastic effects of optical model found by fitting two parameters for proton-induced reactions. The coefficients were determined by least-square fitting method. The obtained cross-section formulas with new coefficients have been discussed and compared with the available experimental data.eninfo:eu-repo/semantics/closedAccess(p, alpha) and (p, np) reaction cross-sectionsempirical formulasoptical modelpairing effectasymmetry term effectArticle74693194310.1007/s12043-010-0085-92-s2.0-77954342704Q2WOS:000279106100008Q3
