Langevin study of neutron emission in the reactions 16O+181Ta and 19F+178Hf
pre-scission neutron multiplicity entrance channel mass asymmetry compound nucleus spin distribution Langevin equation

The pre-scission neutrons measured in the reactions 16O+181Ta and 19F+178Hf are studied via a Langevin equation coupled with a statistical decay model. We find that because of the mass asymmetry of di...
45MeV/A 12C和181Ta相互作用中余核的研究
余核 181Ta 45MeV/A 12C

用厚靶-厚收集箔技术测量了45MeV/A 12C和181Ta相互作用中余核的生成截面和反冲性质,并将实验得到的质量产额分布与统计碎裂模型进行了比较.根据前向平均反冲射程计算了线性动量转移,在与我们以前工作相比较后指出,在45MeV/A 12C离子引起的反应中,中心碰撞的线性动量转移随靶质量而增加,并与引导粒子模型计算结果很好相符.
