title: Determining the angles of incidence in a LEED experiment.
abstract: A new method for determining the angles of incidence in a back-reflection, post-acceleration, fluorescent display LEED apparatus is presented which uses the angles between the diffraction spots on a photograph of the LEED pattern. Absolute accuracies better than 0.1 degrees for both incidence angles should be routinely available.
