| 摘 要： | 对3.7 A GeV 16O与原子核乳胶作用α射弹碎片的发射进行了研究, 发现α射弹碎片的角分布不能用单一的旁观体-反应体模型来解释，所以假设α射弹碎片来源于两个温度不同的发射源。

| Abstract: | The emission of alpha projectile fragments has been studied in 16O-emulsion interactions at 3.7 A GeV.The angular distributions of relativistic alphas cannot be explained by a clean-aut participant-spectator model.Therefore it is assumed that alphas originate from two distinct sources differing in their temperatures. |

| Keywords: | relativistic heavy-ion collision helium projectile fragments angular distribution |
