本文介绍了一种求射线强度函数的新方法-形法。与奥斯陆方法相结合，即使在没有中子共振间距数据的情况下，也可以同时得到核能级密度（NLD）和的斜率。形状方法的基础在于主射线转换，它保留了函数形式的信息。形状法已应用于、、和，这是典型的NLD和研究中遇到的各种情况的代表性案例。形状方法与奥斯陆方法的结果比较表明，无论核结构细节或初级跃迁所提供的态的值如何，函数形式都保持不变。
The shape method, a novel approach to obtain the functional form of the-ray strength function, is introduced. In connection with the Oslo method the slope of the nuclear level density (NLD) andcan be obtained simultaneously even in the absence of neutron resonance spacing data. The foundation of the shape method lies in the primary-ray transitions which preserve information on the functional form of the. The shape method has been applied to,, and, which are representative cases for the variety of situations encountered in typical NLD andstudies. The comparisons of results from the shape method to those from the Oslo method demonstrate that the functional form of theis retained regardless of nuclear structure details orvalues of the states fed by the primary transitions.
