摘　　要：将弹核与靶核看作动量空间的一对费米球,既考虑碎裂过程,又考虑转移过程,对中能重离子核碰撞实验测得的类弹产物动量分布约化宽度数据做模型分析,拟合效果颇佳.A model taking into account both fragmentation and transfer process agrees well with experimental data on projectile-like-products momentum distribution resulting from heavy ion collisions in Fermi energy domain and in relativistic energy domain. The resulted reduced widths σ_0 are given for both fragmentation and transfer process respectively.
