摘要

<正>In the concept of the dinuclear system (DNS) model, the evaporation residue cross section is expressed as a sum over all the partial waves J at the centre-of-mass energy Ecm,σER(Ecm) =πh2/2μEcmΣ(2J+1)T(Ecm,J)PCN(Ecm,J)Wsur(Ecm,J). (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 of
