Zr同位素中的形状共存和宇称二重态

Shape co-existence and parity doublet in Zr isotopes

Bharat Kumar

摘要:

我们从~(12)M开始,用BCS和Bogolyubov对的相对论和非相对论平均场方法研究了Zr同位素从质子到中子滴线的基态和激发态性质。计算中使用名人NL 3和SLy 4参数集。在大多数同位素中,我们发现球形基态和低位^M超形变激发态。在分析超形变^M组态的单粒子能级时,发现了几对^M $Ω^π=1/2^{\pm}$宇称二重态。

英文摘要:

We studied the ground and excited states properties for Zr isotopes starting^M from proton to neutron drip-lines using the relativistic and non-relativistic mean field formalisms with BCS and Bogolyubov pairing. The celebrity NL3 and SLy4 parameter sets are used in the calculations. We find spherical ground and low-lying^M superdeformed excited states in most of the isotopes. Several couples of^M $Ω^π=1/2^{\pm}$ parity doublets configurations are found,^M while analyzing the single-particle energy levels of the superdeformed ^M configurations.
