Determination of K-shell absorption jump factors and jump ratios for La2O3, Ce and Gd using two different methods.

The K shell absorption jump factors and jump ratios for La 2 O 3 , Ce and Gd samples have been determined using the gamma or X-ray attenuation and EDXRF methods. It is the first time that the K shell absorption jump factor and jump ratio have been discussed for present elements using two different methods. To detect K X-rays, a high resolution Si(Li) detector was used. The experimental results of K shell absorption jump factors and jump ratios were compared with the theoretically calculated ones.
