原子核正常形变、超形变和超形变的共存:用angular momentum投影研究

Coexistence of normal, super-, and hyper-deformation in nuclei: A study with angular momentum projection

Yang Sun, Jing-ye Zhang, Gui-Lu Long, Cheng-Li Wu

摘要:

对A~110核的角动量投影能面计算表明,在不同的角动量下有三个不同的能量极小值。这些对应于正常的,超,超变形的形状共存于一个核。本文详细研究了110 Pd的超形变谱,并通过投影壳模型计算对超形变谱进行了定量预测。建议在A-110质量区的其他几个相邻的核,与中子数约64,也表现出明确的超级和超形变极小值。

英文摘要:

Angular-momentum-projected energy surface calculations for A~110 nuclei indicate three distinct energy minima occurring at different angular-momenta. These correspond to normal, super-, and hyper-deformed shapes coexisting in one nucleus. 110Pd is studied in detail, with a quantitative prediction on super- and hyper-deformed spectra by the Projected Shell Model calculation. It is suggested that several other neighboring nuclei in the A-110 mass region, with the neutron number around 64, also exhibit clear super- and hyper-deformation minima.
