We report here a general survey and simple analysis of the nuclear intrinsic quadrapole moments, nuclear deformations and magnetic moment in the rotational model.The results show (See Fig. I) that, in general, most nuclei, including heavy, medium and light ones, are not spherical, and the deformation of many of them is not small, and in several regions the nuclear deformation is persistently large. These areⅠ. A-10, (e.g. 4Be9,6B10,5B11) Ⅱ. A-24, (e.g. 9F19,10Ne21, 11Na28,12Mg24,13Al27)Ⅲ. A-56, (e.g. 25Mn56,36Fe66,36Fe67)Ⅳ....

It is probable that rotational spetra may also exist in the regions Ⅰ, Ⅲ & Ⅳ. We have tentatively calculated the magnetic moments of nuclei up to A = 130, making use of the typical rotational wave function, for the internal wave function, Nilsson's wave function is used. The calculated values are in general better than the Schmidt's value, in many places, especially in the regions of large deformation, the agreement of the calculated value with experimental value is quite good. This fact supports the possibility that the regions of the large deformation Ⅰ, Ⅲ & Ⅳ also possess rotational spectra.

在这里我们给出一个关于原子核固有电四极矩、形变及磁矩的普查与分析工作报告;结果表明(见图1):无论是重核,轻核或者中等核,绝大多数都是非球形的,很多核的形变都不小。在若干区域中,形变普遍地较大。这些区域是: Ⅰ. A~10(_4Be~9 _5B~10 _5B~11等) Ⅱ.A~24(_9F~19·_l0Ne~21._11Na~23._12Mg~24 _13Al~27等) Ⅲ.A~56(_25Mn~55 _26Fe~56·_26Fe~57等) Ⅳ.A~78(_33As~75·_34Se~75·_34Se~79·_35Br~79·_35Br~81·_35Br~82等) Ⅴ.155225,α-放射性元素 其中Ⅴ,Ⅵ及Ⅱ是早已知道的转动区,其他区域中也可能存在着转动能谱。 我们尝试采用转动模型波函数去计算轻核及中等核(A<130)的磁矩(内部粒子波函数采用了Nilsson波函数)计算结果一般都此Schmidt值好,而在相当多的地方,特别是形变较大的核,计算结果则好得多。例如F~19一Al~27大形变核区域便是最好的例子,这一结果加强了大形变区Ⅰ,Ⅲ,Ⅳ也是转动区的可能性。
