Abstract = {{We study the photon energy dependence of Ce-3d photoemission in CeM2
   compounds (M = Fe, Co, Ni) and in Ce7Ni3 with measurements taken with
   synchrotron radiation in the photon energy range 1050-3850 eV. The
   results show a drastic increase of the bulk sensitivity at the higher
   energies due to the increase of the photoelectron escape depth. The
   spectra at 3850 eV are largely dominated by the bulk contribution, which
   is typically 85% of the total intensity in the CeM2 compounds. The
   results allow us to obtain the bulk contribution to the spectra in CeM,
   with a procedure presented here and giving the fractional weights of the
   bulk f(0), f(1), and f(2) configurations. In the CeM2 compounds a
   correlation is found between these spectral weights and the
   crystallographic data showing that the hybridization is nonmonotonic
   versus the atomic number of the transition metal. We discuss the results
   both in connection with an impurity model and with the available
   calculations in an itinerant model. Moreover, the results suggest that
   the bulk hybridization in CeM2 systems with heavy transition metals has
   been probably underestimated up to now.}},
