Deformed nuclei in a chiral model

We investigate the deformation properties of atomic nuclei in a hadronic chiral ${\mathrm{SU}}_{\mathrm{flavor}}\mathrm{}\left(3\right)\mathrm{}$ model approach. The parameters are fitted to hadron mass properties and adjustments for spherical finite nuclei have been performed. Using these parameters the deformation of a series of light and heavy nuclei are obtained in a two-dimensional self-consistent calculation. In addition a case of superdeformation in a heavy nucleus is studied.
