     The level spectrum of collective surface oscillations of even-even nuclei, especially the effect of β-degree of freedom on the level spectrum in the strong coupling theory, is studied. It appears that, except the contribution of a series of β-vibration levels, the effect on other levels is small.
     本文考虑了偶—偶原子核,集体表面振荡的能谱,着重考虑在强耦合理论中β自由度对能谱的影响,发现β自由度除了贡献一部分新的β振荡激发能谱以外,对原有的能谱影响不大。

     "Identical bands" (i. e. those with surprisingly similar moments of inertia) have beenfound through several analyses of known bands in normally deformed nuclei. In this paper, we analyzebands in odd-proton nuclei (A=150~190) and A-1 even-even adjacent nuclei with stringentcriteria. The "identical bands" are found to be associated with upsloping particle states.
     近年来,通过对已知正常形变核转动带的分析,发现了“等同带”(即具有惊人相似的转动惯量),本文利用一个严格的判据,比较了A=150~190质量区奇A核及其相邻A—1偶—偶核的转动带,发现“等同带”对应于奇A核中占据上升轨道的粒子态。

     A discussion on the energy spectra and E2 transition ratios and branching ratios of the even even Ru isotopes with A=98 to A=106 is carried out in the framework of neutron proton Interacting Boson Model. With the quadrupole interacting among like coherent nucleon pairs S and D being taken into account,the staggering phenomenon in the quasi γ bands of these nuclei are improved. The calculated results of the low lying energy levels agree with the experimental data quite will.

Considering the nucleus as an axial asymmetric quantum mechanical system, we have discussed the rotational spectra of even-even nuclei under the adiabatic approximation. The following results are obtained.1. From the detailed analysis of low-lying energy levels of ten nuclei, rotational spectra of axial asymmetric nuclei definitely exist. The theoretical values of energy levels agree with experimental results very well. (See Fig. 1)2. We have obtained the three principal moments of inertia, (?)1, (?)2 and (?)B,...

The following results are obtained.1. From the detailed analysis of low-lying energy levels of ten nuclei, rotational spectra of axial asymmetric nuclei definitely exist. The theoretical values of energy levels agree with experimental results very well. (See Fig. 1)2. We have obtained the three principal moments of inertia, (?)1, (?)2 and (?)B, of ten nuclei (Os190, Os186, W183, Er168, Er166, Dy150, Gd156, Gd154, Pu283, Pu240).3. The relation among the throe moments of inertia, as predicated in Eolir's model, is proved to be incorrect. According fo Bohr's theory, one should haveThereforeBut the values of (?)1, (?)2, and (?)0, deduced from experiments do not satisfy this relation. (See Fig. 3)

把原子核看作一非轴对称量子力学体系,在绝热近似下,考虑了其转动激发能谱。我们只讨论了偶偶核。计算及讨论表明: (1)原子核,特别是重核,肯定存在着非轴对称转动能谱,从我们仔细计算过的十个原子核能谱来看,理论值和实验值符合得很好,(见图1),大多数与实验值的偏离≤1%。 (2)我们第一次求得了原子核(Os~(190),Os~(186),W~(132),E~(166),E~(165),Dy~(160),Gd~(156),Gd~(154),Pu~(238)和Pu~(240))的三个主转动惯量θ_1,θ_2和θ_3。(表1). (3)原子核转动惯量之间并无A.Bohr理论所指出的关系。按照Bohr理论, (θ_1/θ_3)~(1/2)-(θ_2/θ_3)~(1/2)=1 但我们从实验求得的θ_1,θ_2和θ_3并不满足上述关系式(见图3)。

本文用扩散型光学位阱对低能(中子2—4兆电子伏,质子3.5—7兆电子伏)非弹性散射角分布、激发函数和γ射线角分布进行了计算,目的是比较系统地定量检验Hauser-Feshbach理论。计算结果和实验符合得很好。说明H.F.理论中的基本出发点,即不同复合核态之间的干涉相消的假设,是近似成立的。在此基础上,我们进一步讨论了可以用H.F.公式来提供光学位阱参数与能级自旋宇称知识的可能性,后者具体应用至N~(14)的高激发态,计算表明:N~(14)的4.91兆电子伏和5.01兆电子伏能级的自旋分别为0和2,能级的自旋对截面的大小影响很显著,但宇称则几乎没有影响。同时我们也应用H.F.理论讨论了相邻奇-偶核和偶-偶核弹性散射的差异。最后,考虑到同位旋在轻核中是一个准守恆量,本文中研究了在复合核过程中同位旋守恆的可能性,给出了考虑同位旋守恆以后的H.F.公式。并对于N~(14)(p,p′)N~(14)至第一激发态2.31兆电子伏(t=1),和第二激发态3.95兆电子伏(t=0)的非弹性散射角分布,分别在同位旋守恒和不守恒情况下进行了计算,结果表明,不守恒时的计算值和现有的实验非常接近,看来同位旋量子数在轻核的复合核反应中...
