Description
The AMoRE collaboration aims to investigate for rare processes, including neutrinoless double electron capture (0$\nu$2EC), an intriguing alternative to neutrinoless double-beta decay for exploring the fundamental nature of neutrinos. In this study, we present a comprehensive analysis of the 0$\nu$2EC process in $^{40}$Ca, utilizing the high-purity, enriched calcium molybdate ($^{48dep}$Ca$^{100}$MoO$_{4}$) detectors from the AMoRE-I experiment.
Utilizing advantage of the low-background environment and high energy resolution of AMoRE-I setup, we performed a thorough search for 0$\nu$2EC signature at the Q-value (193.51 keV) of the decay. In this presentation, we report studies on the half-life of 0$\nu$2EC in $^{40}$Ca and highlight the sensitivity of low-temperature calorimeters in probing rare decay processes.
