Dynamic Study on Damped Reactions of ^244Pu＋^244Pu,^238U and^238U and ^197Au＋^197Au

In most attempts to produce superheavy elements（SHE）, the complete fusion reactions have successfully been tried. Since the 70＇s the elements from Z=107 to 116 were synthesized in the ＂cold fusion＂ reactions with lead and bismuth targets and ＂hot fusion＂ reactions with actinite targets. However,     

14 ^40，48Ca＋^90，96Zr融合反应的动力学模型研究

应用改进的量子分子动力学模型，在严格挑选初始核考虑弹靶结构效应的基础上，研究了近垒和垒上融合反应^40，48Ca＋^90，96Zr研究表明：4个反应的理论计算截面与实验值很好符合；丰中子反应^40Ca＋^96Zr的垒下融合截面比其他3个反应有明显增强的现象。
