摘　　要：The astrophysical reaction rate of the charged-particleinduced reaction is dominated by the cross section within the Gamow window. The total cross section o-（E） of a charged- particle-induced reaction is known to drops steeply with decreasing energy owing to the Coulomb barrier in the entrance channel：The astrophysical reaction rate of the charged-particleinduced reaction is dominated by the cross section within the Gamow window.The total cross section σ(E)of a chargedparticle-induced reaction is known to drops steeply with decreasing energy owing to the Coulomb barrier in the entrance channel:
