AB: The author considers an electron beam incident on the surface of a molecular crystal whose
energy is of the order of several electron volts. For simplicity, a simple cubic lattice with one
molecule per cell is discussed. The OX and OY axes lie on the surface parallel to the basis
vectors of the crystal d/sub 1/ and d/sub 2/, and the OZ axis is perpendicular to the surface. The
direction of the incident (scattered) electrons is determined by the azimuthal phi /sub 0/ ( phi
/sub f/) and polar theta /sub 0/ ( theta /sub f/) angles. The finite penetration depth of electrons is
described by a phenomenological damping decrement epsilon . An electron undergoing inelastic
scattering which leads to the excitation of an exciton in a k-state is considered.
