论文摘要
引入了形状方法，是一种在没有中子共振间隔数据的情况下获得$γ$ ray强度函数（$γ$ sf）功能形式的新型方法。当与奥斯陆法相关时，同时获得了核水平密度（NLD）的斜率。形状方法的基础在于主要的$γ$ ray转换，该过渡保留了有关$γ$ SF功能形式的信息。形状方法已应用于$^{56} $ fe，$^{92} $ zr，$^{164} $ dy，$^{240} $ pu，这是典型NLD和$γ$ SF研究中各种情况的代表性案例。从形状方法与奥斯陆方法的结果的比较表明，无论核结构细节如何，$γ$ sf的功能形式都是保留的，或者是由主要过渡喂养的状态的$ j^π$值。
The Shape method, a novel approach to obtain the functional form of the $γ$-ray strength function ($γ$SF) in the absence of neutron resonance spacing data, is introduced. When used in connection with the Oslo method the slope of the Nuclear Level Density (NLD) is obtained simultaneously. The foundation of the Shape method lies in the primary $γ$-ray transitions which preserve information on the functional form of the $γ$SF. The Shape method has been applied to $^{56}$Fe, $^{92}$Zr, $^{164}$Dy, and $^{240}$Pu, which are representative cases for the variety of situations encountered in typical NLD and $γ$SF studies. The comparisons of results from the Shape method to those from the Oslo method demonstrate that the functional form of the $γ$SF is retained regardless of nuclear structure details or $J^π$ values of the states fed by the primary transitions.
