Description

We investigate the relevant nuclear matrix element for the neutrino-accompanied double beta decay of 76Ge to the first excited 2+-state in 76Se. We show, that most of the gpp dependence of the matrix element can be removed by the inclusion of the Pauli principle in the QRPA-calculations. The matrix element remains stable in the physical region of gpp and would thus allow to reduce limits of the decay. (author)
