• We discuss on a partial recovery of a symmetry by resonances between the degenerate broken symmetry Hartree-Bogoliubov (HB) wave functions according to the generalized Peierls-Yoccoz projection method. The projected Resonating (Res) HB configuration interaction (CI) equation determines the Res HB CI mixing coefficients and the energy eigenvalues within Goldstone sets. The Res HB CI equation is expected to bring important new features that are not present in the conventional projected HB calculations. For instance, in superconductive and deformed nuclei, rotational bands built on local low energy minima with different deformed shapes may resonate each other. Then, the expressions for the Yoccoz moments of inertia of the respective rotational bands built on the Res MB levels should change drastically owing to this resonance. Our aim of the present paper is to get the approximate expressions which are correct up to the second order in coset SO(2N)/U(N) variable and the Euler angle.
