Observation of beta-delayed fission from Ac-230

beta -delayed fission for Ac-230 was searched. Ra-230 was produced via multinucleon transfer reaction by 60 MeV/u O-18 ion irradiation of Th-232 target. Thin Ra-230-->beta- Ac-230 sources of 10(8) atoms were acquired through radiochemical separations. The mica track detectors were used to record the fission events. The beta -delayed fission nucleus 230Ac was identified via the observed two fission events and the measured gamma -rays spectra. Its beta -delayed fission probability was obtained to be (1.19 +/- 0.85) x 10(-8).
