摘要：

The two-neutrino mode of double beta decay (2 nu beta beta) of Zr-96 is investigated both theoretically and experimentally, The calculations, using the quasiparticle random phase approximation approach, shaw that for Zr-96 the detection of 2 nu beta beta transitions to the two first excited states in the daughter nuclide will be possible in the very new future. On the experimental side, new, most stringent limits on half-lives for the double beta decay of Zr-96 to excited states in Mo-96 have been obtained with a 430 cm(3) 'well-type' germanium detector, They range between 5 x 10(19) and 8 x 10(19) years (90% CL).
