Z-DEPENDENCE OF MASS ATTENUATION COEFFICIENT AT 59.54 KEV PHOTON ENERGY - EXPERIMENTAL ASSESSMENT OF BINDING-ENERGY EFFECTS

Mass attenuation coefficients of 59.54 keV photons were measured in el ements with atomic number ranging from low to high, and including lant hanides whose K-shell binding energies were close to those of incident photons. Comparison with the most reliable data from tabulations in c urrent use reveals some disagreement in the interval of binding energy values close to 59.54 keV. The significant disagreement reported by o ther authors for certain elements was not confirmed by the present inv estigation. (C) 1998 Elsevier Science Ltd. All rights reserved.
