  摘要:在重核反应中的径向自由度的熔合阻止已经为大家所了解很长一段时间了。然而本文将说明,熔合阻止在颈部熔合中也同样存在。我们用双中心液滴模型计算不同径向值和不同颈部系数时的势能,然后通过计算势能对颈部系数在右端点(e=1)时的导数来确定颈部熔合阻止的存在性问题。利用这种方法系统计算了熔合阻止在对称反应时的存在区域。
  
  Abstract: Fusion hindrance in the radial degree of freedom for massive nuclear reactions is known for a long time. However the present work shows that the fusion hindrance also exists in the neck evolution. We calculate the potential at different distances and different neck parameters by the two-center liquid drop model and then check whether fusion hindrance exists in the neck evolution by examing the sign of slope of potential vs. the neck parameter. The area of fusion hindrance in the neck evolution is shown.
