Vertical chromium distributions in the atmospheres of several Ap and Am stars are fitted using detailed modeling of the profiles of CrII lines. The vertical distributions obtained for Ap stars are consistent with Babels results of an investigation of Cr lines in the spectrum of the Ap star 53 Cam. It is shown that the observational data cannot be interpreted in terms of the hypothesis that microturbulent velocity varies with depth. 1
