| description |
The double beta decay of <sup>150</sup>Nd to the first excited 0<sup>+</sup> level of <sup>150</sup>Sm (E<sub>exc</sub> = 740.5 keV) was investigated with the help of the ultra-low-background setup consisting of four HP Ge (high-purity germanium) detectors (≃225 cm<sup>3</sup> volume each one) at the Gran Sasso underground laboratory of INFN (Italy). A highly purified 2.381-kg sample of neodymium oxide (Nd<sub>2</sub>O<sub>3</sub>) was used as a source of γ quanta expected in the decays. Gamma quanta with energies 334.0 keV and 406.5 keV emitted after deexcitation of the 0<sub>1</sub><sup>+</sup> 740.5 keV excited level of <sup>150</sup>Sm are observed in the coincidence spectra accumulated over 16375 h. The half-life relatively to the two neutrino double beta decay <sup>150</sup>Nd → <sup>150</sup>Sm(0<sub>1</sub><sup>+</sup>) is measured as T<sub>1/2</sub> = [4.7<sup>+4.1</sup><sub>-1.9</sub>(stat)±0.5(syst)]×10<sup>19</sup> y, in agreement with results of previous experiments. |
