    Abstract

    Absolute doubly differential cross sections for the ionization of atomic hydrogen by electron impact have been measured at energies ranging from near threshold to intermediate values. The measurements are normalized to the accurate differential cross section for the electron-impact excitation of the H 12S⃗22S+22P transition. These measurements were made possible through the use of a moveable target source which enables the collection of hydrogen energy loss spectra free of all backgrounds. The measurements cover the incident electron energy range of 14.6–40 eV and scattering angles from 12° to 127°, and are in very good agreement with the results of the latest theoretical models—the convergent close-coupling model and the exterior complex scaling model.
