有限核统计衰变向高能的演化

Evolution of the statistical disintegration of finite nuclei toward high energy

A. S. Botvina, N. Buyukcizmeci, M. Bleicher

摘要:

我们发展了一种统计方法来描述高能重离子反应中动态产生的重子形成复杂核的过程。本文考虑了中心核-核碰撞后形成的有限高激发膨胀核系统。该系统被细分为初级平衡核子团簇。最后的原子核是在这些被激发的原子团衰变后产生的。通过与FOPI实验数据的成功比较,我们证明了在相共存区温度下,核物质中存在这种局域平衡的可能性。给出了在这种新的成核机制中得到的平均值。

英文摘要:

We develop a statistical approach for the description of complex nuclei formation from dynamically produced baryons in high energy heavy-ion reactions. We consider a finite highly-excited expanding nuclear system formed after central nucleus-nucleus collisions. This system is sub-divided into primary equilibrated nucleon clusters. The final nuclei are produced after the decay of these excited clusters. By the successful comparison with the FOPI experimental data we prove the possibility of such a local equilibrium in nuclear matter with the temperature corresponding to the phase coexistence region. The regularities obtained in this new nuclei production mechanism are shown.
