Description

An experiment for the detection of 0νβ+/EC in 92Mo nuclei has been carried out with a newly developed scintillating crystal, CaMoO4, surrounded by CsI(Tl) crystals. We study the background events inside the event selection window for 0νβ+/EC decays of CaMoO4 detector. The 92Mo 0νβ+/EC decay half-life limit was set to 2.3x1020 years with a 90% confidence level. A perspective on the current experiment is discussed.
