摘要
本文介绍用中子球探测器测量重离子核反应中的单举中子多重性分布.给出在27、35、44和77MeV/u四个轰击能量下^(40)Ar+^(197)Au,^(40)Ar+^(232)Th两个反应体系的实验结果.单举中子多重性分布反映了在反应过程中不同耗散程度的碰撞的相对贡献.
The inclusive neutron multiplicity distribution in the heavy-ion reactions measured by a 4π neutron detector is presented in this paper. Results for^(40)Ar+^(197)Au and ^(40)Ar+^(232)Th at 27, 35, 44 and 77 MeV/u are displayed. The distribution provides an overview on the reaction characteristics concerning the relative strength of contributions according to their degree of dissipation.
