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 Energies

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.
