✦ Synopsis

High statistic M~ssbauer spectra have been performed at 300K on ten samples of YBa2Cu~.xFe 0-(0.01 ~ x ~ 0.15). Only two fit solutions hold from x 2 factor analysis. It is shown t~at T~ 1-6 is governed by x and by the population of one iron species which could correspond to high coordinated ironsin chains.
