Radioisotope of 230Pa was synthesized by proton irradiation of ThO2 powder targets with thickness of about 2g/cm2. Pure 230Pa was extracted and deep purified from thorium and fission products by the radiociicmical method. Thin 230Pa→β-230 U sources were prepared for measuring the cluster decay of 230U. Two cases of decay via heavy ion emission, which were most probably for the neon decays of 230U, were detected by using solid-state track registration detectors. The preliminary branching ratio relative to α-decay comes out to be (1.3±0.8) × 10-14.
