Astrophysical S-factors and reaction rates of (p,n)-reactions on (117)Sn, (118)Sn, (122)Sn, and (124)Sn

摘要

Astrophysical S-factors and reaction rates were derived from available cross sections of (p,n)-reactions on (117)Sn, (118)Sn, (122)Sn, and (124)Sn isotopes at incident proton energies up to 9 MeV. The statistical theory predictions of the observable quantities are similar to 2 times smaller at near threshold energies and have better agreement at higher energies.
