Description
A technique to search for 2K capture of 78Kr with a large low-background proportional counter filled with a sample of krypton enriched in 78Kr up to 99.8% at a pressure of 4.51 atm is described in this paper. The results of first measurements are presented. An analysis of data collected for 159 h yielded a new limit to the half-life of 78Kr with regard to 2K capture (T1/2 ≥ 1.5 x 1021 yr (90% C.L.)). The sensitivity of the facility to the process for one year of measurement was evaluated to be S = 1.0 x 1022 yr (90% C.L.)
