Experimental observation of [Formula: see text]Si as a proton bubble nuclei has heated up the interest in the study of exotic bubble shaped nuclei. In this work, some of the potential doubly bubble-like (for proton as well as neutron both simultaneously) cases have been explored using relativistic Hartree–Bogoliubov (RHB) in light mass region, specially around N or [Formula: see text]. Further, the role of pairing and the evolution of new shell gaps around [Formula: see text] or [Formula: see text] and 34 have been investigated, as one moves toward drip lines. This study suggests that the occupancies/vacancies of neutron/proton orbitals for lower angular momentum state plays major role in nuclear structure to create bubble-like structure and [Formula: see text]O[Formula: see text], [Formula: see text]Mg8 and [Formula: see text]Si[Formula: see text] may have dual bubble-like structures.

由相对论 Hartree-Bogoliubov 模型预测的可能的双泡状结构

[公式：见正文]Si作为质子泡核的实验观察引起了人们对奇异泡状核研究的兴趣。在这项工作中，已经使用相对论 Hartree-Bogoliubov (RHB) 在轻质量区域，特别是在 N 附近或 [公式：见文本] 探索了一些潜在的双重气泡状（同时用于质子和中子）情况。此外，已经研究了配对的作用以及 [公式：见文本] 或 [公式：见文本] 和 34 周围新壳间隙的演变，随着人们向滴水线移动。这项研究表明，较低角动量状态的中子/质子轨道的占位/空位在核结构中起主要作用，形成气泡状结构，[公式：见正文]O[公式：见正文]，[公式：见正文]镁8和[公式：见正文]Si[公式：见正文]可能具有双重气泡状结构。
