Abstract

230Pa was produced with the reaction 232Th (p, 3n) 230Pa in the irradiation powder targets of ThO2 with 35 MeV proton beam. Sources of 230Paβ-230U were prepared by radiochemical method. Using solid-state track registration detectors, two events of 230U decay with heavy cluster emission have been observed. The preliminary branching ratio to α-decay comes out to be B = λNeα = (1.3 ± 0.8) × 10-14.
