高j中子与质子在transfermium核中转动排列的竞争

Competition in rotation-alignment between high-j neutrons and protons in transfermium nuclei

摘要:

准粒子转动-排列的研究灵敏地探测了高j入侵者轨道的性质。超高j轨道的分布是基本自旋轨道相互作用的结果,它与超重核单粒子能级的重要问题相联系。利用标准Nilsson势产生的变形单粒子态,我们对目前可以进行详细光谱实验的transfermium核进行了投影壳模型计算.具体地说,我们研究了Cf,Fm和No同位素的旋转排列和相关的带交叉现象的系统行为。从高j轨道的中子和质子被发现竞争强烈的旋转对齐,这引起了可测试的效果。对这些效应的观测将提供最重核质量区单粒子态的直接信息。

英文摘要:

The study of rotation-alignment of quasiparticles probes sensitively the properties of high-j intruder orbits. The distribution of very high-j orbits, which are consequences of the fundamental spin-orbit interaction, links with the important question of single-particle levels in superheavy nuclei. With the deformed single-particle states generated by the standard Nilsson potential, we perform Projected-Shell-Model calculations for transfermium nuclei where detailed spectroscopy experiment is currently possible. Specifically, we study the systematical behavior of rotation-alignment and associated band-crossing phenomenon in Cf, Fm, and No isotopes. Neutrons and protons from the high-j orbits are found to compete strongly in rotation-alignment, which gives rise to testable effects. Observation of these effects will provide direct information on the single-particle states in the heaviest nuclear mass region.
