摘要 利用两步模型,计算了在不同碰撞能量下30Si+238 U反应的准裂变质量碎片分布.这是第一次尝试用两步模型去计算准裂变碎片质量的分布.计算结果与实验数据相比,符合得非常好,说明了该模型的合理性. The mass distributions of fragments of quasi - fission of the reaction 30 Si + 238 U culated at different bombard energies. It's the first time of using the two- step model to products of quasi - fission. And the experiments data are reproduced well,which shows the the model.
