论文摘要
我们开发了一种统计方法,用于描述高能重型离子反应中动态产生的重子的复杂核形成。我们考虑了中央核核碰撞后形成的有限兴奋的扩展核系统。该系统被细分为主要平衡的核子簇。这些激发簇的衰减后产生最终核。通过与FOPI实验数据的成功进行比较,我们证明了在核物质中具有这种局部平衡的可能性,温度与相位共存区域相对应。显示了在这种新核生产机制中获得的规律性。
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.
