Abstract
A new and independent confirmation of ββ(2ν) decay of 100Mo to the first 0+ excited state in 100Ru has been made. This was accomplished using a two-photon coincidence counting technique in which two HPGe detectors were used to observe the two emitted γrays (E γ1 = 590.8 keV and E γ2 = 539.6 keV) from the daughter nucleus as it deexcites to the ground state (0+ → 2+ → 0+). The half-life of this decay has been estimated as ∼(5–8)×1020 yr.Keywords
