摘要
本文介绍了裂解-聚合反应机制对核反应能谱的中段连续谱的贡献。这个反应机制认为炮弹在靶核势场中经历了裂解及与靶核聚合两步过程。本文给出了一个处理裂解-聚合机制的有限程计算的理论方法,并把这一理论应用于α粒子轰击轻重不同的靶核的一系列核反应。理论与实验的比较证实裂解与聚合反应机制是对中段连续谱的主要贡献。
Contribution from the breakup--fusion mechanism to continuum spectra of nuclear reac- tion is introduced. In this mechanism a two-step process is considered in which the projectile breaks up to two pieces in the field of target, and fusion of one piece with the target is follo- wed. A method of finite range calculation is presented. The comparison of theoretical calcula- tion with experimental data is shown for reactions on light and heavy targets bombarded by α--projectile. The results show that the breakup--fusion rnechanism mainly contributes to conti- nunm spectra.
