摘要

利用三轴投影壳模型方法(TPSM)对奇质量\(^{123-131}\)镧同位素负奇偶价带进行了理论研究。势能表面(PES)计算表明这些同位素具有\(\gamma \) -软性质。对它们的四极形状不变量的分析进一步支持了这一发现,这表明原子核具有软三轴形状。利用与前人研究一致的合适变形参数,生成了yrast波段、\(\gamma \) -波段及其特征伴星的能带能量。各波段带头能量与实验值吻合较好。此外,还计算了带图、惯性矩反向弯曲、动态惯性矩、特征分裂和减少跃迁概率(B(E2)和B(M1))等结构性质。

Theoretical investigation of near yrast bands in odd-mass \(^{123-131}\)La isotopes

Theoretical investigation of negative parity bands in odd-mass \(^{123-131}\)La isotopes has been carried out by using Triaxial Projected Shell Model approach (TPSM). Potential Energy Surface (PES) calculations suggest \(\gamma \)-soft nature of these isotopes. This finding is further supported by an analysis of their quadrupole shape invariants, which indicates that the nuclei have a soft-triaxial shape. Suitable deformation parameters, which are in agreement with the previous studies, are used to generate the band energies of the yrast band, \(\gamma \)-band, and their signature partners. The bandhead energies of all the bands are in good agreement with the experimental values. Further, structural properties like band diagrams, backbending in moment of inertia, dynamic moment of inertia, signature splitting and reduced transition probabilities (B(E2) and B(M1)) have also been calculated.
