Energy dispersive X-ray spectroscopy has insufficient resolution to separate the individual lines of low energy L-series peaks. However, the mass absorption coefficients for Lα and Lβ radiation differ significantly for elements with atomic numbers between 21 and 32. Effective mass absorption coefficients for the entire L-shell emission were determined by measuring the variation of the X-ray intensities emitted from pure element standards, as a function of the accelerating voltage, and fitting the experimental data with a theoretical curve using the XMAC software. These experimentally determined mass absorption coefficients were compared with average values calculated on the basis of the theoretical line intensities, taking into account the primary vacancy generation and the radiationless Coster-Kronig transitions.
