中能核反应阻止本领的研究

A study of stopping power in nuclear reactions at intermediate energies

G. Lehaut, D. Durand, O. Lopez

摘要:

本文利用中心对称核反应中的INDIGITAL数据,对阻止本领进行了系统的实验研究。系统的总质量从80到400个核子,而入射能量范围从12 AMeV到100 AMeV。本文还讨论了在GANIL进行的32和45 MeV/核子124,136 μ π ι射弹对112,124 Sn靶的同位旋扩散的作用。结果表明一个强大的记忆的入口通道以上20 AMeV/A(核透明度),因此,构成有价值的测试的微观运输模型。

英文摘要:

We show a systematic experimental study based on INDRA data of the stopping power in central symmetric nuclear reactions. Total mass of the systems goes from 80 to 400 nucleons while the incident energy range is from 12 AMeV to 100 AMeV. The role of isospin diffusion at 32 and 45 MeV/nucleon with 124,136Xe projectiles on 112,124Sn targets performed at GANIL is also discussed. Results suggest a strong memory of the entrance channel above 20 AMeV/A (nuclear transparency) and, as such, constitute valuable tests of the microscopic transport models.
