I present a theory of the orientation and alignment of atoms observed upon emergence from tilted foils. The interaction with the foil surface is taken into account in the production process of particular states. Once they are produced, the evolution of these states, under the influence of the residual field near the surface, is calculated in the fashion introduced by Eck. The most general effect of this evolution is presented.

The polarisations of four excited levels in 40 Ar + ions have been measured at different times after excitation in a beam-tilted-foil experiment. Within the uncertainties typical of present beam-foil work, the possible transfer of polarisation resulting from optical cascades has no observable effect on time-resolved quantum-beat measurements.
