Abstract = {{We present photoemission results with uv and with x rays from a family
   of pseudobinary compounds obtained by partial substitution of Yb, with
   Ca or Sc, in the reference compound YbAl2.  The substitution with Ca
   gives rise to a decompression and the one with Sc a compression of the
   lattice.  Ultraviolet photoemission shows the perturbation of the
   electron states due to chemical substitution; Sc introduces a d
   character extending up to about 3 eV below the Fermi level.  The weights
   of the Yb3+ and Yb2+ multiplets given by x-ray photoemission are
   compared with the results from x-ray absorption; the two spectroscopies
   agree in YbAl2 while the relative weights Yb3+ versus Yb2+ from x-ray
   photoemission are definitely below the x-ray-absorption values in the
   compounds heavily substituted with Sc; this is interpreted as a
   photoemission final-state effect connected with the d character
   introduced by the substitution.}},
