摘要：

A model based on chiral SU(3) symmetry in nonlinear realization is used for the investigation of nuclei, superheavy nuclei, hypernuclei, and metastable, exotic multistrange nuclear objects (so-called MEMOs). The model works very well in the case of nuclei and hypernuclei with one A particle and rules out MEMOS. Basic observables that are known for nuclei and hypernuclei are reproduced satisfactorily. The model predicts Z = 120 and N = 172, 184, and 198 as the next shell closures in the region of superheavy nuclei. The calculations have been performed in self-consistent relativistic mean-field approximation assuming spherical symmetry. The parameters were adapted to known nuclei.
