Abstract
An explicit analytic expression for the propagator of a coherent motion of an exciton in a semi-infinite linear chain is derived. The “surface” relaxation is studied and the probability of an exciton being captured at the surface is calculated. The possibility of using the exponential decay approximation and the generalization to the three-dimensional crystal are also discussed.
