摘要

The path-integral effective-potential (EP) method was applied to the calculations of EXAFS cumulants. The EXAFS cumulants up to the fourth order for diatomic Br_2 were evaluated and compared to the results by the first- and second-order perturbation theory and also the experiments. The second-order perturbation formulas for the even-order cumulants (C_2 and C_4) are newly presented. The advantages and disadvantages of the EP method are discussed.
