The complete L2MM and L2MM Auger spectra of selenium have been observed using an X-ray photoelectron spectrometer. The relative energies of all components are shown to be in agreement with calculations which use the binding energies of core levels and tables of atomic integrals, intermediate coupling being assumed for the two-hole final states. The total relaxation accompanying LMM Auger processes in solid Se is independent of the two-hole final state and has been found to be 23.8+or-2.0 eV. This includes a total atomic contribution estimated as 14.6+or-1.0 eV of which 7.4+or-0.2 eV arises from relaxation in the outer shell. The contribution from intra shell relaxation is deduced to be 7.2+or-1.2 eV and from extra-atomic processes as 9.2+or-3.0 eV. This analysis of the relaxation is supported by measurement of an Auger line from the L3MN series.
