Abstract
Two neutrino double beta decay of 150Nd
to the first 0+ excited state in 150Sm is investigated with
the 400 cm3 low-background HPGe detector. Data analysis for
11320.5 hours shows the excess of events at 333.9 keV and 406.5 keV.
This allowsto estimate the half-life of the investigated
process as
yr.
