Resumen:
We evaluated the nuclear matrix elements (NME) unperturbed and perturbed for transitions 2 and 0. We considered the contributions weak-magnetism and pseudo-tensorial in the hadron current. Within the QRPA and with the procedure previouslydescribed, we used the parameter t = tsym, given fairly well results of jM2j in comparison with the experimental values. We known that when the BCS equations are solved, the isospin symmetry is broken. This symmetry is partially restored when we include the proton-neutron correlations on the ground state through of QRPA
