Abstract

By using the recoil-fission correlation technique, the exotic process of beta-delayed fission (βDF) was unambiguously identified in the very neutron-deficient nuclei ^192,194At in experiments at the velocity filter SHIP at Gesellschaft fur Schwerionenforschung (GSI). The upper limits for the total kinetic energy release in fission of ^192,194Po, being the daughter products of ^192,194At after beta(+)/EC decay, were estimated. The possibility of an unusually high beta DF probability for ¹⁹²At is discussed.
