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.
