Nuclear Deformation Effects of Highly Charged Ions — •Zewen Sun, Igor A. Valuev, and Natalia S. Oreshkina — Max Planck Institute for Nuclear Physics, Heidelberg, Germany

Nuclear shape effects are theoretically investigated in terms of corrections to the electronic binding and transition energies and g factors. The corrections are numerically calculated for the widest possible range of nuclei, consisting over 1100 different samples. By solving the Dirac equation with deformed and non-deformed nuclear shapes, i.e. Fermi and deformed Fermi nuclear charge distributions, we separate the deformation effect in binding energies and wavefunctions. The model parameters for the two charge distributions are determined from experimental data. In addition, the importance of deformation effects for the process of searching for new physics is examined.
