Search for 2K(2 nu)-capture of Xe-124

摘要

The results of a search for two neutrino mode of double K-capture of Xe-124 using a large copper low-background proportional counter are presented. Data collected during 3220 hours of measurements with 58.6 g of Xe-124 provides us to a new limit on the half-life of Xe-124 regarding 2K-capture at the level: T (1/2) ae 2.0 x 10(21) years at a 90% confidence level.
