Abstract

Photoelectron and (e, 2e) experiments are compared under limiting conditions. The results of an (e, 2e) experiment in the helium autoionizing region are presented. Spectra taken for ejected electron directions 180° apart are analyzed using a new technique involving fundamental magnitudes and phases. It is shown that although all quantities may not be deduced from the experimental data, reliable values may be obtained for the net magnitude and phase of the summed non-resonant even parity amplitude relative to those of the resonant dipole amplitude.
