Abstract
New limits on double beta processes in Mo-92 have been obtained using a 400 cm(3) HPGe detector and an external source of high-purity natura l molybdenum. At confidence level CL = 90% they are 1.9 . 10(20) y for the (Ov + 2v)beta(+)EC transition to the ground state, 8.9 . 10(20) y and 8.1 . 10(20) y for the (Ov + 2v)ECEC transitions to first excited 2(1)(+) and 0(1)(+) states in Zr-92, correspondingly.
