| 1. | ( 3 ) . there exists a deficiency of the axial symmetry rotor plus two quasi - particles model for odd odd nuclei that the vibration far away from the inversion point is smaller ( 3 ) .在研究奇奇核的二准粒子加轴对称转子模型中,存在着远离旋称反转点两端的劈裂幅度偏小的缺点。 |
| 2. | ( 2 ) . the calculations further confirm that the competion between the coriolis force and n - p coupling interaction in the low k space might be the possible dominating mechanism for si in odd odd nuclei ( 2 ) .进一步证实了在低k空间中, n - p相互作用与科氏力的竞争是奇奇核旋称反转的一种可能的主要机制。 |
| 3. | According to the off - line rnb ' s requirement of the radioactive isotope , the doubly odd nucleus 64cu produced by reactor was chosen as the first nuclide to carry out expermental research about the off - line rnb 按照离线放射性核束对放射性同位素的要求,我们把堆照放射性同位素样品~ ( 64 ) cu作为首选核素来开展离线放射性核束的实验研究工作。 |
| 4. | We could draw an elementary conclusion : triaxial shape plays an important role to cause si in odd odd nuclei and its influence will become stronger in some nuclei which have 100 126 large g deformation , such as rh and la . ( 4 ) 初步得出结论:三轴形变是引起奇奇核旋称反转现象的重要因素。 100126在部分三轴形变比较大的核中,作用会更强。譬如rh 、 la 。 |
| 5. | Since the magic number 28 , which is the first that requires the introduction of a strong spin - orbit interaction belongs to the if2p shell in the nuclear shell model . so the nuclei in the if2p shell have been a research hotspot in nuclear physics . the doubly odd nucleus 64cu which is also in the if2p shell has been the subject of many experimental investigations previously via various type of nuclear reaction such as 64ni ( p , ny ) and its excitation leveles have been already studied to about 8 mev 放射性核素~ ( 64 ) cu是奇奇核,属于1f 、 2p壳层,而在原子核壳模型中,第一个需要引入强自旋-轨道藕合才能出现的幻数就在1f 、 2p ? ?壳层,因此if 、 zp壳层一直是核物理领域的研究热点,近三、四十年来使用了各种不同类型核反应例如‘ 4ni … , fly )等反应,对‘ ll激发态性质进行了广泛的研究,其激发能级已到了smev左右。 |
| 6. | In this paper , we first introduce the basic background of the study of nuclear structure , some elementary knowledge about and the latest achievements in the study of the phenomena of signature inversion ( si ) . then the description of the two quasi - particles plus a rotor model ( prm ) of odd odd nuclei is given . by the model we perform the practical calculations of the yrast bands of some nuclei in a 100 , 130 mass region 本文首先简要介绍了原子核结构研究的一些基本概况以及与旋称反转现象相关的一些基本知识和奇奇核旋称反转现象的最新研究进展;然后较详细地介绍了用于奇奇核旋称反转研究的二准粒子加转子模型( prm ) ,着重对a 100 、 130质量区中的几个奇奇核的晕带能谱进行了实际prm计算,结合计算结果,讨论了旋称反转、三轴形变以及反转机制等相关问题。 |
