关于重离子碰撞TBCTT和QMD两种理论计算结果的系统比较

Systematic Comparisions of Theoretical Calculation Resultson Heavy Ion Collision Between TBCTT and QMD

为了检验基于两体关联动力学而建立的关于重离子碰撞的两体关联输运理论（ＴＢＣＴＴ）．对ＴＢＣＴＴ和量子分子动力学（ＱＭＤ）的理论计算结果在不同入射道条件下进行了仔细的比较。结果表明：所计算的各种物理量的时间演化过程，对两种理论而言得到了非常相似的行为，这说明ＴＢＣＴＴ是一个具有很好发展前景的重离子碰撞动力学的输运理论。

In ordor to test the two-boody correlation transport theory (TBCTT), which is established for heavy ion collisions based on the two-boody correlation dyanmics, detailed comparisons between the preliminary numerical results of TBCTT and those of quantum molecular dynamics (QMD) am performed, and it is shown that all behaviors of quantites studied for different incident conditions of heavy ion collision are very similar for two theories. This implies that the TBCTT theory is promising for the description of heary ion collision dynamics with selfconsistent inclusion of fluctuation effects.
