摘要：

KX-Ray-gated and time resolved emission Mossbauer spectra of 57Co-labeled Co(IO3)2 were measured at room temperature, using a coincidence technique. No remarkable difference was found on the relative intensity of Fe(II)/Fe(III) between the X-ray-gated and normal emission spectra. A lifetime for unstable 57Fe(II)-species formed through EC-decay was estimated to be 43±5 ns and the initial distribution of Fe(II)/Fe(III) at 14.4 keV nuclear level to be 0.47±0.13 from the time-resolved emission Mossbauer spectrum. The results are discussed in terms of the chemical stability of the environments of the decayed 57Fe-atoms. © 1988 The Chemical Society of Japan.
