Experimental x-ray spectra of the Cl L-2,L-3 absorption edge for free NaCl
clusters of various sizes are presented. X-ray absorption spectra of the Na
4Cl4 cluster have been theoretically calculated by the total multiple scatt
ering method. A distorted cube is determined as the most probable geometric
structure of the Na4Cl4 cluster. Curves of the partial densities of states
are obtained for the cluster. (C) 2000 MAIK "Nauka/Interperiodica".
