【Abstract】 On the basis of the cluster shell model of double well,a new method for subs-tracting the kinetic energy of the relative motion of the fission fragments has beenproposed,and in this way the potential energy curve for spontaneous fission of ~8Behas been calculated.In the calculation,the effects of the coulomb potential and thespurious states of the motion of the center of mass have been considered properly.The results can qualitatively explain the metastable property of ~8Be.It seems thatthe method proposed in this paper might serve as a way to describe the fisson processin microscopic study.更多还原
