周边碰撞和中心碰撞中碎片分配产生的比较

Comparison of fragment partitions production in peripheral and central collisions

E. Bonnet, B. Borderie, N. Le Neindre, M. F. Rivet

摘要:

本文分析了在外围碰撞和中心碰撞中产生的分别对应于准抛射源和准聚变源的单源事件的集合。在对碎片运动学性质进行选择后,利用量热法导出了源的激发能,并比较了两个系综碎片的平均行为。在它们的分区中观察到的差异,特别是电荷不对称性,可以与碰撞过程中沉积在系统中的集体能量有关。

英文摘要:

Ensembles of single-source events, produced in peripheral and central collisions and correponding respectively to quasi-projectile and quasi-fusion sources, are analyzed. After selections on fragment kinematic properties, excitation energies of the sources are derived using the calorimetric method and the mean behaviour of fragments of the two ensembles are compared. Differences observed in their partitions, especially the charge asymmetry, can be related to collective energy deposited in the systems during the collisions.
