Abstract = {{Photoemission spectra of pseudobinary Yb(1-x)M(x)Al2 (M = Sc, Ca)
   compounds derived from YbAl2 are given (hv = 40.8, 65, 181.5 and 1253.6
   eV) at various stoichiometries corresponding to compressed (with Sc) and
   decompressed compounds (with Ca). The surface divalent Yb 4f signal
   depends on the chemical substitution and is stronger in the compressed
   compounds (2.9 times with respect to YbAl2 in the case of 80% Sc
   measured at 40.8 eV). Auger results are also reported. The effect is
   discussed in connection with the release of compression energy in the
   surface region.}},
