ResumoUsing photoelectron spectroscopy, we have measured some relative partial photoionization cross sections in He and Ne atoms. By compiling these results, along with previously published data obtained from photoabsorption, photoion and photoelectron spectroscopies, we have determined accurate absolute partial photoionization cross sections, up to 300 eV photon energy. The absolute scale was obtained by normalization to the photoabsorption cross sections. The best recommended values, determined by this self-consistent experimental procedure, are compared with the results of various theoretical determinations of the photoionization cross sections.
