Two body Transport Theory of Heavy Ion Collisions

摘要: 对中能重离子碰撞的两体关联输运理论、它的Ｈｉｅｒａｒｃｈｙ截断和守恒定律进行了研究．该理论包括了时间相关的平均场、两体关联和Ｐａｕｌｉ原理，并且时间相关的平均场和两体关联动力学之间在自洽耦合和非耦合两种情况下进行了数值计算和讨论．初步计算结果表明，两体关联输运理论能对重离子碰撞动力学过程进行合理的描述，总粒子数、总动量和总能量基本上守恒，从而表明该理论是一个很有发展前景的输运理论． The Two body Correlation Transport Theory (TBCTT), its several hierarchy truncations and conservation laws for intermediate energy heavy ion collision have been investigated. This approach contains time dependent mean field, two body correlation effects and Pauli principle, the self consistent coupling between time dependent mean field and two body correlation dynamics is emphasized and preserved in realistic numerical calculation by a set of coupled dynamical equations...Abstract: The Two body Correlation Transport Theory (TBCTT), its several hierarchy truncations and conservation laws for intermediate energy heavy ion collision have been investigated.
