The shape coexistence description by mean-field and beyond
mean-field methods
A new method to restore symmetries on mean-field wave functions and to treat
quantum mechanically the vibrations with respect to a collective mode by
configuration mixing has been recently set up. The basic ingredients of the
method will be reviewed. Application to different region of the nuclear
chart (in particular to nuclei around neutron deficient Pb isotopes) will be
discussed.
