摘要：

A position-sensitive detector has been constructed and mounted at the exit of an electron spectrometer. This allows the simultaneous accumulation of a larger part of the energy-loss spectrum. As an example we measured the spin asymmetry for excitation of mercury atoms by polarized electrons. The energy-loss peaks for excitation of the Hg 6**3P//0//,//1//,//2 states were detected simultaneously for positive and negative electron polarization.
