  The influence of large amplitude pairing fluctuations is investigated in the
framework of beyond mean field symmetry conserving configuration mixing
calculations. In the numerical application the finite range density dependent
Gogny force is used. We investigate the nucleus $^{54}$Cr with particle number
and angular momentum projected wave functions considering the axial quadrupole
deformation and the pairing gap degree of freedom as generator coordinates. We
find that the effects of the pairing fluctuations increase with the excitation
energy and the angular momentum. The self-consistency in the determination of
the basis states plays an important role.
