重离子全熔合反应中的能量相关位垒

Energy-dependent Barrier in Heavy-ion Induced Fusion Reaction

摘要: 本工作采用能量相关的位垒穿透模型分析了１２Ｃ、１４Ｎ、１６Ｏ、３２Ｓ、３５Ｃｌ和４０Ａｒ等重离子全熔合激发函数数据，提取了势函数Ｅ１、Ｖ１、Ｅ２、Ｖ２、Ｒｂ和ｈω．数据分析表明，能量相关的位垒穿透模型能够满意地复现全熔合截面随能量变化的行为． The complete fusion excitation function for several systems formed by 12C, 14N, 16O, 32S, 35Cl and 40Ar ion with some targets have been analysed by an energy-dependent bsrrier penetraction model. The potential parameters E1, V1, E2, V2, Rb and Hω have been extracted from the experimental daal. It Shows that the energy-dependent barrier penetraction model can describe sads factorily the behaviour of the change of the fusion cross section with the bombstding energy.
