摘要

Background: Adouble-K-electron capture is a rare nuclear-atomic process inwhich twoK electrons are captured simultaneously from the atomic shell. A "hollow atom" is created as a result of this process. In single-K-shell electron-capture decays, there is a small probability that the second electron in the K shell is excited to an unoccupied level or can (mostly) be ejected to the continuum. In either case, a double vacancy is created in the K shell. The relaxation of the double-K-shell vacancy, accompanied by the emission of twoK-fluorescence photons, makes it possible to perform experimental studies of such rare processes with the large-volume proportional gas chamber.
