Relativistic computations of ${L}_{1}$-MM, ${L}_{2}$-MM, and ${L}_{3}$-MM Auger spectra have been carried out in the intermediate coupling with configuration interaction for a final two-hole state and j-j coupling for an initial state. Results for ten elements with 18\ensuremath{\le}Z\ensuremath{\le}92 are listed and compared with experimental data. Good agreement with the scarce experimental data is attained. The effect of correlation is shown to shift some of the Auger energies by as much as \ensuremath{\sim}15 eV. The effect of final-ionic-state configuration interaction is found to increase the ${L}_{3}$-${M}_{1}$${M}_{1}$ rate by a factor of \ensuremath{\sim}2 for Z\ensuremath{\le}45. Intermediate coupling is necessary to analyze the L-MM Auger spectra for 30\ensuremath{\le}Z\ensuremath{\le}80. As in the case of K-${M}_{1}$${M}_{4}$,5 transition calculated ${L}_{1}$-${M}_{3}$${M}_{3}$${(\mathrm{}}^{3}$${P}_{2}$) and ${L}_{3}$-${M}_{1}$${M}_{4}$,5 intensities as functions of Z are found to peak sharply in the neighborhood of Z=63 due to the strong level-crossing interaction. This interaction is found to increase the ${L}_{1}$-${M}_{3}$${M}_{3}$${(\mathrm{}}^{3}$${P}_{2}$) intensity at Z=60 by a factor of 50.
