dc.descriptionWe show how the longstanding problem of the collapse of the charge-exchange QRPA near the physical value of the force strength can be circumvented. This is done by including the effect of ground state correlations into the QRPA equations of motion. The corresponding formalism, called renormalized QRPA, is briefly outlined and its consequences are discussed in the framework of a schematic model for the two-neutrino double beta decay in the $^{100}Mo \rightarrow\, ^{100}Ru$ system. The question of the conservation of the Ikeda sum rule is also addressed within the new formalism.
