We investigated resonant absorption of gamma quanta in the compounds CeFe2Si2 and CeFeSi, which have magnetic-ordering temperatures 700 and 440 K, respectively. The character of the Mossbauer spectra demonstrates identity of the electronic states of the iron atoms and an anomalous absence of effective magnetic fields at their nuclei.
