中高能核反应中的热化

Thermalization in Intermediate high Energy Reactions

摘要: 用微观动力学模型研究了中高能核反应中的热化．对８３０ＭｅＶｐ＋５６Ｆｅ和３５ＭｅＶ／ｕ^４０Ｃａ＋^４０Ｃａ反应的研究表明，反应系统基本上达到了统计热平衡．发现两核碰撞过程中存在明显的横向流． Thermalization in intermediate high energy reaction is studied by microscopic kinetic model. The calculations are carried out for reactions 830 MeV p+ 56 Fe and ⁴⁰Ca ( E =35 MeV/u )+⁴⁰Ca. The calculations show that the quasi equilibrium can be reached. It is found that there is an obvious transverse flow in the nucleus nucleus reaction process.
