Theoretical approaches that use one-body densities as dynamical
variables, such as Hartree-Fock or the density functional
theory (DFT), break isospin symmetry both explicitly, by virtue of
charge-dependent interactions, and spontaneously. To restore
the spontaneously broken isospin symmetry, we implemented the isospin-projection
scheme on top of the Skyrme-DFT approach. This development allows for consistent
treatment of isospin mixing in both ground and exited nuclear
states. In this study, we apply this method to evaluate the
isospin impurities in ground states of even-even and odd-odd nuclei. By including simultaneous isospin
and angular-momentum projection, we compute the isospin-breaking corrections to the
superallowed -decay.
