We have studied the deformation systematics of [Formula: see text] and [Formula: see text] values, yrast spectra, band structure and backbending phenomena in the neutron-deficient even–even [Formula: see text]Cd isotopes within the projected shell model (PSM) framework. The observations of the systematics of [Formula: see text] and [Formula: see text] values for [Formula: see text]Cd isotopes are well reproduced in present calculations. Our observations show that, as we move from [Formula: see text]Cd to [Formula: see text]Cd, the deformation increases and then it reduces up to [Formula: see text]Cd. This gives us a confirmation that [Formula: see text]Cd is the most deformed nucleus in this set of isotopic mass chain. The backbending phenomena is also observed in these isotopes, which can be related to the crossing of ground band (g-band) by 2-quasiparticle (qp) bands or s-bands. The pseudomagic character of [Formula: see text]Cd has also been observed.

投影壳模型框架内缺中子偶-偶100-110Cd同位素核结构动力学的微观研究

我们研究了[公式：见正文]和[公式：见正文]值、yrast谱、能带结构和中子缺乏偶数-偶数[公式：见正文]Cd同位素在投影壳内的变形系统学模型（PSM）框架。[公式：见正文]和[公式：见正文][公式：见正文]Cd同位素的系统学观察值在目前的计算中得到了很好的再现。我们的观察表明，当我们从 [公式：见文本]Cd 移动到 [公式：见文本]Cd 时，变形增加，然后减小到 [公式：见文本]Cd。这给了我们一个确认[公式：见正文]Cd是这组同位素质量链中变形最大的原子核。在这些同位素中也观察到后弯现象，这可能与 2-准粒子 (qp) 带或 s 带与基带 (g-band) 的交叉有关。[公式：见正文]Cd的伪魔特性也被观察到。
