Abstract

Combined x-ray diffraction and x-ray absorption results arepresented on the substitutional Ce valence transition inCeNixCu5-x as a function of applied externalpressure. No significant influence of pressure on the valencein the near-transition region of x is found in the crystalstructure or in the Ce K-edge position. This result isdiscussed in the context of valence instabilities inintermetallic Ce compounds.
