Determination of K-shell absorption jump factor for some elements using EDXRF technique

The K-shell absorption jump factor is measured using an energy dispersive X-ray fluorescence spectrometer for several elements including Nb, Tc, Ru, Rh, Cd, In, Sn, Te, Pr, Pm, Sm, Eu, Gd, Tb, Dy, Ho and Er. The experimental absorption jump factors are compared with the theoretical estimates of Broll (X-Ray Spectrom. 15 (1986) 27 1) based on the fundamental parameter method. Good agreement is observed between experimental results and theoretical estimates in the 41 less than or equal to Z less than or equal to 68 atomic region. Experimental absorption jump factors have been evaluated using the experimental fluorescence cross-sections measured by Budak et al. (Nucl. Instrum. Methods 149 (1999a) 379) and Karabulut et al. (Nucl. Instrurn. Methods 152 (1999) 202). The K-shell absorption jump factors are fitted to simple linear and compared with theoretical, fitted and XCOM values. (C) 2003 Elsevier Science Ltd.
