摘要
用动力学与统计相结合的模型和统计模型分别研究了形变对重同量异位素200Ag,200Tl,200Bi和轻同量异位素110Pd,110In,110Te断前粒子发射的影响．计算表明形变的影响是存在的,但形变却并没有改变中子和带电粒子发射对系统同位旋的依赖关系．对可能的原因也进行了讨论．
The effect of deformation on pre-scission particle emission of three heavy isobaric systems,^200Ag,^200Tl,^200Bi, and light isobaric systems, ^110Pd,^110In,^110Te are investigated by the combined dynamical statistical model and the statistical models, respectively. The calculated results show that deformation has an effect on the isospin dependence of particle emission, but it does not change the dependence of different particle emission on the isospin of the systems. Possible reasons are discussed.
