Description
Cross sections for simultaneous photoionization of He and excitation to He+(n=2) have been measured from threshold to 160 eV. The data show clear evidence of autoionization from levels converging on He+(n=3). Away from such structure, they are in good agreement with previous experimental values. None of the theoretical predictions gives the correct magnitude at low energies
