Theoretical backscattering amplitude and phase functions, B(k) and phi(k), used in extended x-ray-absorption fine structure (EXAFS) studies show strong features in their k dependence which can be identified as a ''generalized Ramsauer-Townsend effect.'' This effect is studied in detail for elements with atomic number 78less than or equal toZless than or equal to90.
