摘要

在协变密度泛函理论（CDFT）的框架下，利用DD-ME2和DD-PC1参数化研究了偶偶92−130Ru同位素的形状演化。采用轴向和三轴势能面（PES）计算来考察基态形状的演变以及同位素链上形状转变和共存现象的发生。此外，系统地研究了各种基态性质，包括结合能、双中子分离能、电荷半径和双中子壳层间隙。结果表明，随着中子数的增加，核变形逐渐发展，与现有的实验数据一致。

Microscopic description of the shape evolution in Ru isotopes

The shape evolution in even-even ⁹²⁻¹³⁰Ru isotopes is investigated within the framework of covariant density functional theory (CDFT), using the DD-ME2 and DD-PC1 parametrizations. Axial and triaxial potential energy surface (PES) calculations are employed to examine the evolution of ground-state shapes and the occurrence of shape transitions and coexistence phenomena across the isotopic chain. Additionally, various ground-state properties, including binding energies, two-neutron separation energies, charge radii, and two-neutron shell gaps, are systematically studied. The results reveal a gradual development of nuclear deformation with increasing neutron number, and demonstrate robust agreement with available experimental data.
