Skyrme能量密度泛函在深度垒下熔合反应中的初步应用

Application of Skyrme Energydensity Functional to Fusion Reactions at Deep Subbarrier Energie

摘要: 基于Skyrme能量密度泛函并对动能密度按扩展的ThomasFermi半经典近似展开到四阶项，探索了深度垒下熔合反应的熔合截面急剧下降现象。通过分析熔合反应的入射道势和熔合截面来选择Skyrme参数，进而探索了深度垒下熔合反应与核物质状态方程之间的关系。The Skyrme energydensity functional together with the extended semiclassical ThomasFermi method is applied to the study of heavy ion fusion reactions at deep subbarrier energy. The relation between heavy ion fusion reactions at deep subbarrier energy and the equation of state (EOS) of nuclear matter is further probed by selecting different sets of Skyrme force parameters to reproduce the experimental excitation functions.
