L-level widths due to the Auger and radiative processes are calculated for light metals such as Al, Mg and Na by using a theory of soft X-ray emission developed by Morita and Watabe in terms of the Green’s function method. Results are nearly consistent with level widths observed experimentally. It is explained that L1–L2,3 emission line spectra have very weak intensities and L1-emission band spectra cannot be observed. The calculated intensity ratios between L3- and L2-emission band spectra are nearly equal to two, the degeneracy ratio of these two levels, while the observed intensity ratios are much larger than two. It is suggested that the observed large values of the ratio may be attributed to the self-absorption effect on the L2-band emission.
