Abstract
We try to give a theoretical analysis of 2νβ-β- decay to the final excited 2+ states by considering SU(4) symmetry restoration within the framework of quasi-particle random phase approximation (QRPA). Pyatov's method is used to restore the symmetry violations stemming from the mean-field approximation. A comparison of the calculated decay rates with other calculations and the corresponding experimental data is given. [ABSTRACT FROM AUTHOR]
