A theory describing slow excitons which interact with longitudinal optical lattice vibrations is developed within the framework of the effective mass approximation. In many respects the theory is very similar to --and makes explicit use of --the ordinary theory of polarons which is used here in Gura
## Abstract The migration in a crystal of spatially inhomogeneous electronic excitations interacting with a phonon thermostat is studied. The evolution of excitons with band widths of the order of the optical phonon energy or greater is shown to be adequately described by a mixed, siteβenergy repre
