Abstract
Experimental and theoretical study of Al K-XANES in AlPO4 (berlinite) and in KAl(S04)212H2O(K-alum) with
different types of Al environment is performed. Calculations proved that the experimental XANES are well reproduced within
EXAFS-like approach to electron scattering description i.e. considering the single-, double- and triple-scattering processes on
two and approximately linear three-atoms chains originated at Al-absorbing atom and consisting mainly of O-atoms chosen
under the same for both compounds empirical "selection rule".
