Description

A technique to search for 2Κ capture of 78Kr with large low-background proportional counter filled with an enriched in 78Kr up to 99.8% at a pressure of 4.51 atm is described. The results of first measurements are presented. Analysis of data collected during 159 h yielded new limit to the half-life of 78Kr with regard to 2Κ capture (T1/2 ≥ 1.5 x 1021 yr (90% C.L.))

Abstract (Russian)

Описывается методика поиска 2Κ-захвата в 78Kr в большом низкофоновом пропорциональном счетчике, заполненном этим изотопом до обогащения 99.8% при давлении 4.51 атм. Описываются результаты измерений. При анализе данных, полученных в течение 159 ч, определен новый предел полупериода относительно 2Κ-захвата T1/2 ≥ 1.5 x 1021 лет при 90%-ном уровне достоверности
