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^β-_→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 = λ_Ne/λ_α = (1.3 ± 0.8) × 10^-14.
