Abstract

In experiments performed at the GSI Fragment Separator and at the GANIL SISSI-LISE3 facility the decay of ⁴⁵Fe has been investigated. Implantation events of ⁴⁵Fe ions, stopped in silicon telescopes, were correlated with radioactive decay events. The decay energy spectra exhibit a peak of an average energy of (1.14 ± 0.05) MeV. This observation, together with the non-observation of coincident γ or β events, represent clear evidence for the two-proton ground state decay of ⁴⁵Fe. The average half-life of ⁴⁵Fe, deduced from both experiments, is T_1/2 = 3.8_-0.8^+2.0 ms.
