摘要：
An electron spectrometer especially designed for the study of elastic scattering has been constructed and used to measure absolute differential elastic cross sections of 500-eV electrons scattered from He, CO, and N 2. Comparison with calculated values for He indicates that the first Born approximation with exchange gives results which agree with experiment to within 2% at angles greater than 18°. At small angles the observed cross sections exceed the calculated by a large factor. The cross sections for N 2 and CO change with angle in very similar ways.
