Application of Skyrme Energydensity Functional to Fusion Reactions at Deep Subbarrier Energie
-
摘要: 基于Skyrme能量密度泛函并对动能密度按扩展的ThomasFermi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 energydensity functional together with the extended semiclassical ThomasFermi method is applied to the study of heavy ion fusion reactions at deep subbarrier energy. The relation between heavy ion fusion reactions at deep subbarrier 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.
