title: Observation and removal of higher-order (ghost) energy-loss lines present in Mollenstedt electron velocity analyzers.
abstract: Mollenstedt electron velocity analyzers, used in high-energy electron impact spectroscopy, have been found to be limited by higher-order (ghost) energy-loss lines superimposed upon the real energy-loss spectrum. The origin of these ghost lines, as well as a method of removing them experimentally, is discussed.
