摘要：

The asymmetry parameter beta has been obtained for ionization into the He+ (N = 2) states as a continuous function of photon energy in the region of autoionizing states from 69-77 eV. Differential cross sections at 0-degrees and 90-degrees have been measured using a sensitive photoelectron spectrometer in conjunction with monochromatized synchrotron radiation. The deduced beta variation is presented along with the measured cross section at 90-degrees.
