用半经典模型考虑20Ｎａ＋２０８Ｐｂ→ｐ＋１９Ｎｅ＋２０８Ｐｂ的Ｃｏｕｌｏｍｂ解离过程。用ＭｏｎｔｅＣａｒｌｏ方法计算前角放置的望远镜阵列对Ｃｏｕｌｏｍｂ解离碎片的探测效率。讨论了天体环境下ｐ＋１９Ｎｅ→２０Ｎａ俘获反应道的低能级共振截面测量的可行性。
The Coulomb dissociation of 20Na + 208Pb → p + 19Ne + 208Pb is considered by the semi-classical model. The Monte Carlo method was used to calculate the detection efficiency of Coulomb dissociation fragments by the telescope arrays placed in the anterior horn. The feasibility of low-level resonance cross-section measurement of p + 19Ne → 20Na trapping channel in celestial environment was discussed.
