Abstract
In this work we present new improved experimental limits for the partial half-lives of the double beta processes of (96)Ru and (104)Ru, obtained by means of a γ-ray spectrometry measurement. A disc of metallic Ru of natural isotopic abundance was sandwiched between two HPGe-detectors in the 225 m deep underground laboratory HADES. After 108 days of measurement, the lower bounds for the partial half-lives were up to 6.9×10(19) yr for (96)Ru and 1.9×10(20) yr for (104)Ru.
