Abstract
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 particle and rules out MEMOs. Basic observables that are known for nuclei and hypernuclei are reproduced satisfactorily. The model predicts and 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.
