A many-body Hamiltonian involving the mean field for a projected spherical single-particle basis, the pairing interactions for alike nucleons, and the dipole-dipole proton-neutron interactions in the particle-hole (ph) channel and the ph dipole pairing potential is treated by the projected gauge fully renormalized proton-neutron quasiparticle random phase approximation approach. The resulting wave functions and energies for the mother and daughter nuclei are used to calculate the 2\ensuremathν\ensuremathβ\ensuremathβ decay rate and the process half-life. For illustration, the formalism is applied for the decay 100Mo\ensuremath→100Ru. The calculated half-life is in agreement with the corresponding experimental data. The Ikeda sum rule is obeyed.
