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 ²³⁰Pa -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 decay comes out to be B=λ_Ne/λ_α=(1.3±1.8)×10^－14.
