Abstract：
β-delayed fission for ^230Acwas searched. ²³⁰Ra was produced via multinucleon transfer reaction by 60MeV/u¹⁸O ion irradiation of ²³²Th target. Thin ²³⁰Ra→β-²³⁰Ac sources of 108 atoms were acquired through radiochemical separations. The mica track detectors were used to record the fission events. The β-delayed fission nucleus ²³⁰Ac was identified via the observed two fission events and the measured γ-ray spectra. Its β-delayed fission probability was obtained to be (1.19±0.85)×10^－8.
