Abstract
The EXAFS function is directly estimated by the numerical integration in order to determine a precise
anharmonic pair potential without utilizing a cumulant expansion. Ge (Ge K-edge) and CuBr (Cu K-edge) selected as weak
and strong anharmonic materials, respectively, were investigated to compare differences of potential values determined by
the present integral method and the conventional cumulant method.
