Abstract
The existence of strong variations in the total secondary electron current with incident beam direction from a tungsten (110) surface can be explained on the basis of the observed angular distribution of the secondary emission and the reciprocity theorem. We propose a dynamical two-beam model based on the variation of electron absorption in the crystal as a function of the diffraction conditions.Keywords
