Differential cross sections describing the correlated motion of three
electrons in the nuclear Coulomb field during the complete photofragme
ntation of a four-body system, the lithium atom, are calculated. Two s
election rules are derived and their operation illustrated. Two featur
es, not present in the corresponding three-body case are emphasized, n
amely that the Wannier configuration, in contrast to the three-body ph
otofragmentation of helium, is allowed. Second, the cross section to a
ccess certain spin-momentum configurations of the three particles is z
ero for an uncorrelated but finite for a correlated final state.
