Abstract
EXAFS measurements on and above the CsL(III) absorption edge were
performed in LiCsSO(4) (LCS) and in the system
Li(1.44)Rb(0.11)Cs(0.45)SO(4) (LRCS), aiming at the identification of
the local symmetry around Cs ions in this new mixed metal sulphate LRCS.
EXAFS simulations were also carried out and the results of the LRCS
agrees well with recent single-crystal x-ray diffraction measurements,
confirming that a new crystalline phase is expected for the mixed system
LiCsSO(4)-LiRbSO(4). Copyright (C) 2002 John Wiley Sons, Ltd.
