Simulation of the detecting efficiency in the reaction 50MeV/u20Na+208Pb→p+19Ne+208Pb
【摘要】 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。
【Abstract】 The detecting efficiency of Coulomb dissociation fragments by a givendetector-array placed at very forward angle has been calculated by usingMonte--Carlo simulation based on a semi-classic description of the Coulombdissociation 50MeV/u 208Na+,2208Pb-p + 19Ne + 208Pb. The feasibility of measuring theresonance cross section of the capture reaction p+ 19Ne~20Na in stellar environmentwas discussed.
