Abstract
Resonances in the elastic scattering are studied in a scattering experiment at an angle of 72 deg for He and Ne and in a transmission experiment for He, Ne, Kr, and Xe. These resonances result from a compound state of the rare-gas atom and occur about 0.5 eV below the first excited state. The magnitude of the resonances can be enhanced in a transmission experiment when only the unscattered electrons are observed. It is pointed out that the resonance in helium can be used for a determination of the apparent electron energy distribution and as a calibration point on the electron energy scale.Keywords
