Abstract: Compton profiles for $\gamma$- and $\alpha$-Cer were measured using Cr51 as a $\gamma$-radiation source. The experimental profiles have been corrected for multiple scattering by Monte-Carlo technigues. The corrected profiles are compared with theoretical profiles which are calculated on the basis of the renormalized free atom model for 6s electrons and the tight-binding model for 4f and 5d electrons. The experimental results show clearly that the promotional model is not valid. Instead a possible explanation for the observed phase transition may be a Mott transition. To better determine this, improved electron wave functions, such as might be obtained by band structure calculations, are needed.
