摘要：

In this study, we have investigated the asymmetry term effect for the (p,n alpha) reaction cross-sections and we have obtained new coefficients for the (p,n alpha) reactions at 24.8 and 28.5 MeV energies. We have suggested empirical formulas including the new coefficients found by fitting two parameters for proton induced reactions. The coefficients were determined by least-squares fitting method. The obtained cross-section formulas with new coefficients have been discussed and compared with the available experimental data. (C) 2008 Elsevier Ltd. All rights reserved.
