| 摘 要： | 文章在前期工作liang et al1] Ap＜4的轻复杂粒子入射的基础上,对16,17,18,19,20,21,23O入射与各种靶核发生反应的全反应截面进行系统学研究,通过考虑能量相关和原子核质量数相关,获取了一套100 MeV/核子以下不同能量入射的核-核反应全反应截面计算模型.所得模型计算结果不仅与氧入射全反应截面实验数据相符合,同时不改变原来Ap＜4的全反应截面模型的计算结果.

| Abstract: | Based on the former work of our research team liang et al1],which developed a general semi-empirical formula to calculate the reaction cross section for D,3He and 4He as projectiles,we considered the dependence of the incident energy Ein,the mass number of the projectile Ap and the mass number of the target At,and then developed a general semi-empirical systematic model for 16,17,18,19,20,21,23O as projectiles.With the model the reaction cross section can be calculated for a series of target with different isotopes of oxygen as projectiles and different energy incident.The theoretical results with this model can fit both the experimental data of 16,17,18,19,20,21,23O as projectiles and the experimental data of D,3He and 4He as projectiles. |
