Abstract

The search for the beta-delayed fission in neutron-rich nuclei has been performed at the IRIS mass-separator. The delayed fission has not been observed: the limits of probabilities for 228,230,232 Fr and 232 Ac precursors have been obtained. The new isotopes 232 Fr, 233,234 Ra have been identified.
