Abstract

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