Abstract

A lifetime of unstable57Fe(II)-species formed through EC-decay of57Co-labeled Co(IO3)2 was estimated using a coincidence technique. KX-ray-gated and time-resolved emission Mössbauer spectra were measured at room temperature. No remarkable difference was found ont he relative intensity ratio of57Fe(II)/57Fe(III) between the X-ray-gated and time-integral emission spectra. A mean lifetime of the unstable57Fe(II)-species was estimated to be 43±5 ns from the time-resolved emission Mössbauer spectroscopy.
