摘要: 本文对高能核核碰撞中相对论性α粒子的双温度发射现象提出了一种解释，给出了α粒子的角分布，并与２．１ＤｅＶ／ｕ１６Ｏ和１．７ＧｅＶ／ｕ５６Ｆｅ与核乳胶相互作用的有关实验结果作了比较． An explanation on the two-temperature emission of relativistic a particles in high energy nucleus-nucleus collsisions is presented. The angular distributions of a particles are obtained and compared with the exprimental results of 2. 1GeV/u 16O-Em and 1. 7GeV/u 56Fe-Em interactions.
