用变形Skyrme-Hartree-Fock方法研究了从~8Be到~（40）Ca的偶偶核中含有2、4、6和8个超子的多超核的形变，发现当加入2或8个Λ超子时，形变减小，这些差异是由于超子逐渐填充到三个变形p轨道中，其中[110]1/2~-轨道是扁形变的，而简并的[101]1/2~-和[101]3/2~-轨道是扁形变的。
The deformations of multi- hypernuclei corresponding to even-even core nuclei ranging from ~8Be to ~(40)Ca with 2,4,6,and 8 hyperons are studied using the deformed Skyrme-Hartree-Fock approach.It is found that the deformations are reduced when adding 2 or 8 Λ hyperons,but enhanced when adding 4 or 6 Λ hyperons.These differences are attributed to the fact that hyperons are filled gradually into the three deformed p orbits,of which the [110]1/2~- orbit is prolately deformed and the degenerate [101]1/2~- and [101]3/2~- orbits are oblately deformed.
