This paper investigates the cascade down to the ground state of a μ- meson captured by an atom of solid lithium. The cascade takes place predominately through three processes. These are radiation transitions, Auger transitions involving the K shell electrons of the mesonic atom, and Auger transitions involving the band electrons of the solid. It is assumed that the meson is captured in a state of high principal quantum number (n ~ 15). It is found, independant of the number of K shell electrons remaining in the mesonic atom that the principal decay paths follow, at least approximately, and if the meson is captured in a high λ state, the route △n=△i = -lλ.
