Anomlous Anisotropies of Fission Fragments in Near-and Sub-barrier Fusion-fission Reactions
-
摘要: 系统总结了研究近垒和垒下重离子熔合裂变反应碎片各向异性的异常的结果 ,提出一个新的预平衡裂变模型,成功地解释了碎片各向异性的异常现象 .但对异常宽峰结构不能说明 ,有待进一步研究. Systematic summary on the anomalous anisotropies of fission fragments in near and sub barrier fusion fission reactions is presented. A new version of the preequilibrium fission model is put forward to explain the anomalous anisotropies of fission fragments, except the bump of anomaly. Further study is still needed.Abstract: Systematic summary on the anomalous anisotropies of fission fragments in near and sub barrier fusion fission reactions is presented.
