- Abstract
- We report extended x-ray-absorption fine structure measurements performed at the LaKedge and the ULIII
edge of 11 samples in the UxLa12xS system. All samples have the simple NaCl fcc crystal structure. The
measurements reveal a complex local variation of the first-~NN! and second-neighbor~NNN! distances. The
La-S distancesdLaSare systematically larger than the U-S distancesdUSand almost concentration independent
forx<0.5. Around this concentrationdLaSstarts to decrease linearly withx. The study of the second-neighbor
distances confirms a non-Vegard behavior of the lattice parameter evolution with La substitution. Nearx
;0.5 the static disorder in the solid solution strongly increases. (literal)
