    "abstract": "We show that it is possible to restore the symmetry associated with the\nGoldstone mode within the Self Consistent Random Phase Approximation (SCRPA)\napplied to the three-level Lipkin model. We determine one and two-body\ndensities as very convergent expansions in terms of the generators of the RPA\nbasis. We show that SCRPA excitations correspond to the heads of some\nrotational bands in the exact spectrum. It turns out that the SCRPA eigenmodes\nfor N=2 coincide with exact solutions, given by the diagonalisation procedure.",
