Abstract

By using a ²²⁵Ac source produced at the electromagnetic separator Isolde we collected on our track-recording glass detectors 305 ¹⁴C events from the radioactive decays of ²²⁵Ac and its daughter ²²¹Fr and obtained, for ²²⁵Ac, a branching ratio B(¹⁴C/α) = (6.0 ± 13) × 10^-12. Our result suggests that such a decay from an odd proton nucleus is dominated by transition to the ground or to the first excited state of daughter nucleus.
