Abstract
Mass absorp-tion coefficients have been measured for Sc, Ti, V, Fe, Co, Ni, Zn for photon energies from 1.49 to 15.77 keV with an average standard deviation of the mean of 1.2 per cent. A high intensity X-ray beam was provided by a partially evacuated, Bragg-crystal spectrometer. The absorbers were cold-rolled from spectroscopic grade material with thickness determined by the weight-area measurement method. An empirical equation relating photon energy and mass absorption coefficient is proposed for photon energies between the L- and K-absorption energies of the absorber. This equation is used to predict values of mass absorption coefficients for Pb, Sn, Cu and Ca.
