Comparison of atomic and solid-state Auger spectra suggests that the relative intensities of various features in the M<sub>4,5</sub>N<sub>4,5</sub>N<sub>4,5</sub> spectra of Xe and Cd are very similar in the solid and free atom, while in Zn Coster-Kronig transitions from the L<sub>2</sub> level appear to be of some importance in the metal, though not allowed in the free atom. The conditions under which Coster-Kronig rates are enhanced in metals are discussed in terms of extra-atomic relaxation, and the large intensity ratio of L<sub>3</sub>M<sub>4,5</sub>M<sub>4,5</sub>/L<sub>2</sub>M<sub>4,5</sub>M<sub>4,5</sub> processes in Co, Ni and Cu metals may then be readily understood.
