摘要
最近报道的^(185)Pt核多带结构的实验结果,又一次提出了其中五条带回弯现象究竟是由于h_(9/2)质子对转动排列所致,还是来自于i((13)/2)中子对转动排列结果的尖锐问题.基于阻塞效应的实验事实支持前者,而总罗斯量(转动坐标系中的总能量)面的理论计算则支持后者,本文在分析上述两种解释的前提条件的基础上,给出考虑了带交叉过程动力学效应的理论计算结果.说明了h_(9/2)质子对转动排列应是这五条带出现回弯的根源.
The observation of multi-band structure in nucleus ^(185)Pt reported recently, once again raises the open question about whether the alignment of proton h_(9/2) pair or neutron i_(13/2) pair should be responsible to the backbending in five bands. Blocking experiments prefer the proton h_(9/2) pair while the Total Rothian Surface calculation supports neutron i_(13/2) pair. Based on the analysis of assumptions implied in both approaches, a new theoretical calculation which includes the dynamic effect of band crossing is presented. Such a calculation indicates that the alignment of proton h pair should be the main cause for the observed backbendings.
