摘要:

用自洽形变Hartree-Fock(HF)和角动量(J)投影模型研究了偶偶$^{148-160}$ Nd核的转动结构.研究了基态、最近观察到的$K=4^{-}$、$K=5^{-}$和一些激发态、正宇称带和负宇称带的光谱,直到高自旋值。除了这些详细的电磁特性(如E2,M1矩阵元素)的所有频带已获得。我们的模型计算和现有的实验数据之间有很大的协议。对这些核的能带结构和电磁性质进行了预测。预测了一些4-准粒子K-同质异能带及其电磁性质。

英文摘要:

Rotational structures of even-even $^{148-160}$Nd nuclei are studied with the self-consistent deformed Hartree-Fock (HF) and angular momentum (J) projection model. Spectra of ground band, recently observed $K=4^{-}$, $K=5^{-}$ and a few more excited, positive and negative parity bands have been studied upto high spin values. Apart from these detailed electromagnetic properties (like E2, M1 matrix elements) of all the bands have been obtained. There is substantial agreement between our model calculations and available experimental data. Predictions are made about the band structures and electromagnetic properties of these nuclei. Some 4-qasiparticle K-isomeric bands and their electromagnetic properties are predicted.
