Abstract

We analyzed low-background data from the CRESST-II experiment with a total net exposure of 730 kg days to extract limits on double electron capture processes. We established new limits for ⁴⁰Ca with T_1/2 ^2v2K > 9.9 × 10²¹ y and T_1/2 ^0v2EC > 1.4 × 10²² y and for ¹⁸⁰W T_1/2 ^2v/2K > 3.1 × 10¹⁹ with y and T_1/2 ^0v2ED > 9.4 × 10¹⁸ y at 90% CL. Depending on the process, these values improve the currently best limits by a factor of ∼1.4-30.
