论文摘要
核的形状是基本核特性之一。我们对气泡核进行了系统的研究，该核在HF，W，W，OS，PT和HG均匀的同位素中也表现出形状共存，并使用持续体中的变形相对论Hartree-Bogoliubov理论。对于系统的研究，我们首先要分别考虑核泡结构和形状共存。我们确认，通过将我们的结果与相对论连续体Hartree-Bogoliubov理论进行比较的结果，变形和配对相关性阻碍了气泡结构。然后，我们预测具有气泡结构和形状共存的候选同位素。我们观察到，表征气泡结构的耗尽分数大多在固定变形上大多要小于碎屑，而某些同位素（例如$^{206} $ OS）具有扁平和pr酸变形的气泡结构。我们比较了形状共存的质子单粒子能级，既有岩体气泡结构，又具有扁平和扁平的气泡结构。
The shape of a nucleus is one of fundamental nuclear properties. We perform a systematic investigation of bubble nuclei that also exhibit shape coexistence in Hf, W, Os, Pt and Hg even-even isotopes using the deformed relativistic Hartree-Bogoliubov theory in continuum. For a systematic study, we first consider nuclear bubble structures and shape coexistence separately. We confirm that deformations and pairing correlations hinder bubble structures by comparing our results with those from relativistic continuum Hartree-Bogoliubov theory that assumes spherical symmetry in nuclei. We then predict candidate isotopes with both bubble structure and shape coexistence. We observe that the depletion fraction factor that characterizes bubble structure is mostly smaller in oblate deformation than in prolate, while some isotopes such as $^{206}$Os have bubble structures both in oblate and prolate deformations. We compare the proton single-particle energy levels for the candidates of shape coexistence both with only prolate bubble structure and with prolate and oblate bubble structures.
