The Giant Dipole and Pygmy Dipole strengths distributions in the chain of the double-even ^144−154Nd nuclei were investigated using a translational and Galilean invariant quasiparticle random phase approximation (TGI-QRPA). Through the cross sections, transition probabilities and other properties, such as the splitting behaviors of the electric dipole response between the $K=0$ and $K=\pm 1$ components of the electric dipole response were investigated. The predicted concentration of the Giant Dipole Resonance (GDR) exhausts than 99% of the energy weighed sum rules (EWSR) below 20 MeV. Where up to the energy 8 MeV the highly-fragmented E1 strength was predicted. The calculations revealed that neutron excess together with deformation significantly increases the total low-energy E1 strength, while when increasing the deformation, $K=0$ fills the Pygmy Dipole Resonance (PDR) region more strongly than $K=\pm 1$. Here also through nucleon structures such as collectivity and isospin structure of the excitations were presented discussion on differences between PDR and GDR region for neodymium isotopes. In addition, our results reveal that the spin-flip M1 strengths exhibit a broad distribution between 5 and 8 MeV and occupy less than 8% of the total dipole strength in that energy region.

使用平移和伽利略不变准粒子随机相位近似 (TGI-QRPA)研究了双偶^144-154 Nd 原子核链中的巨偶极子和侏儒偶极子强度分布。通过横截面、跃迁概率和其他属性，例如电偶极子响应的分裂行为$钾=0$ 和 $钾=\pm 1$研究了电偶极子响应的分量。巨偶极共振 (GDR) 的预测浓度在 20 MeV 以下消耗了超过 99% 的能量加权总和规则 (EWSR)。在高达 8 MeV 能量的情况下，预测了高度碎片化的E 1 强度。计算表明，中子过剩和变形显着增加了总低能E 1 强度，而当增加变形时，$钾=0$ 填充侏儒偶极子共振 (PDR) 区域比 $钾=\pm 1$. 这里还通过核子结构，例如激发的集合体和同位旋结构，讨论了钕同位素的 PDR 和 GDR 区域之间的差异。此外，我们的结果表明，自旋翻转M 1 强度表现出 5 到 8 MeV 之间的广泛分布，并且在该能量区域中占总偶极子强度的不到 8%。
