摘要：
Mossbauer emission spectra of a Co-57:ZnSe powder source at low temperature exhibit the overcompensated Fe1+ state of the nucleogenic daughter ion generated as an after effect of the Co-57(EC)Fe-57 decay. We analyse to what extent the model of competing acceptors is able to account for the formation and fraction of Fe1+ and present evidence for the role of hole trapping by zinc vacancies.
