Abstract:

The zero energy reflection coefficient of electrons at a freshly evaporated silver surface has been measured to be 7 or 1. The coefficient rises linearly with 39 eV over more than 0.5 eV. Particular care is taken that only those electrons which have actually interacted with the surface are counted those which have been reflected by the applied field without interaction with the surface are not counted. This is accomplished by 1 use of a total energy spectrometer and 2 simultaneous recording of the energy spectrum and target current. Therefore, the reflection coefficient determined is essentially that for orthogonal incidence. This report is intended as a critical discussion of the experimental method the measured coefficient is thought to be caused by reflection in the patches, and agrees with the value to be reported in a subsequent paper.
