Abstract
Precision photoionization cross sections for He have been measured fro m threshold to 120 eV with an accuracy ranging from 1 to 2%. In additi on, a critical review of the published data has been made and recommen ded photoionization cross sections from the ionization threshold to 8 keV are presented with an estimated uncertainty of +/- 10% above 500 e V. The effect of coherent (Rayleigh) and incoherent (Compton) scatteri ng is discussed.
