摘要

Two-neutrino double beta decay (2vββ) half-lives to the first excited state are calculated in the framework of quasi random phase approximation.The quadrupole transition probabilities and the 2vββ decay amplitudes to the final ground states are reproduced by using adjustable parameters.The obtained half-lives are compared with the corresponding experimental data.
