(1) Here T(Ecm,J) is the probability of the colliding nuclei to overcome the potential barrier in the entrance channel. PCN(Ecm,J) is the probability that the reaction system will evolve from a configuration of two touching nuclei after the capture stage into a compound nucleus. The last term is the survival probability 关 键 词：变形影响 截面 超重核 细胞外间质 生产 雌激素受体 ECM 双核系统
