The negative parity bands in the odd-mass Palladium (Pd) nuclei in mass region A ∼110 are known to be built on the deformation-driving $h_{11/2}$ neutron orbital. They offer rich testing grounds for the present day models as well as provide good base to study the deformation systematics of this mass region along with the other nuclear structure properties. Motivated by this, we have taken up the study of odd-mass isotopic chain of ⁹⁹⁻¹¹⁷Pd by applying the theoretical framework of the Projected Shell Model. The results are obtained for the negative parity yrast cascades in these nuclei as well as the on the reduced electric transition probabilities. The quasi-particle structure of these bands has been understood in terms of the band diagrams in which the rotational phenomenon like band-crossing is also discussed. The E-GOS plots along with the R_2/1 and R_3/2 ratios predict the quasi-deformed structure for these bands.

已知质量区域 A ∼ 110 中奇质量钯 (Pd) 核中的负奇偶带建立在变形驱动上。 $H_{11/2}$中子轨道。它们为当今的模型提供了丰富的试验场，并为研究该质量区域的变形系统以及其他核结构特性提供了良好的基础。受此启发，我们通过应用投影壳模型的理论框架对^99-117 Pd的奇质量同位素链进行了研究。结果是针对这些核中的负奇偶校验级联以及降低的电跃迁概率获得的。这些带的准粒子结构已经根据带图来理解，其中还讨论了像带交叉这样的旋转现象。E-GOS 与 R _2/1和 R _3/2一起绘制 比率预测这些带的准变形结构。
