Measurement of K-shell absorption jump factors and jump ratios in some lanthanide elements using EDXRF technique
چکیده انگلیسی

59.5 keV gamma rays scattered by an aluminum foil have been used as a radiation source to measure the absorption jump factor and jump ratios for absorbers Ce, Pr, Nd, Sm, Eu and Tb. The theoretical and experimental values are compared with the corresponding ones in the literature.


► Mass attenuation coefficients, jump factor and jump ratio for lanthanide elements are obtained.
► The method used in this experiment is combined both transmission and scattering geometry.
► Secondary gamma rays energy is 59.5 keV.
► Experimental values of jump factor and jump ratio for K shell are new.
► The experimental values are in good agreement with those calculated theoretically.
