摘要

本文利用含密度依赖介子交换(DD-ME2)和密度依赖点耦合(DD-PC1)参数集的协变密度泛函理论(CDFT)研究了偶偶18-36Ne同位素的形状转变和四极变形的发展。在Ne同位素链中观察到一个突然的形状转变,这可能与单粒子轨道壳结构的演化有关。在其他物理观测中,形状转变和不连续之间的相关性也被检查。我们对基态性质的计算结果与现有的实验数据和各种理论模型的结果吻合得很好。目前的计算推断出在34Ne处的中子滴线。除了形状转变外,还研究了该链中幻核的气泡结构。

A study of shape transition and bubbleness in Ne isotopes
We have studied shape transition and development of quadrupole deformation in even-even 18-36Ne isotopes by employing covariant density functional theory (CDFT) with density-dependent meson exchange (DD-ME2) and density-dependent point coupling (DD-PC1) parameter sets. A sudden shape transition is observed in the Ne isotopic chain and can be related to the evolution of shell structure of single-particle orbitals. The correlations between shape transition and discontinuity in the other physical observables are also examined. Our results for ground-state properties are in good agreement with the available experimental data and the result of various theoretical models. The present calculations infer the neutron drip line at 34Ne. In addition to shape transition, the bubble structure is also studied for magic nuclei in this chain.
