摘要：

An interpretation of X-ray emission spectra for FeAl is given using the results of an augmented plane wave (APW) bandstructure calculation for the simple spectra Fe-K, Fe-L2.3 and Al-K as well as for the composite Fe-M2.3 Al-L2.3 spectrum, for which it is important to take into account non-radiative transition rates, ionisation probabilities and absorption corrections to estimate the relative intensities of these two spectra. Due to these effects the present calculation finds that the Fe-M 2.3 intensity is weakened by a factor of about 200 with respect to the Al-L2.3 spectrum. The theoretical intensity ratio of these two spectra is found to be about half the experimental ratio.
