中文摘要：

为 ≈ 的 Angular-momentum-projected 精力表面计算110 个原子核显示发生在不同 angular-momenta 的三不同精力最小。这些对应于正常，超级 -- ，并且亢奋 -- 使变形的形状在一个原子核共存。110 Pd 详细被学习，与使超级变形和超上的量的预言，由投射的壳的系列当模特儿计算。与在 64 附近的中子数字，在 A-110 集体区域的几个另外的附近的原子核也展出，这被发现清楚超级变丑并且在投射计算的超最小。

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 found 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 in the projected calculation.
