Abstract

The photoionization cross section of helium is calculated by a numerical analytic continuation of the frequency-dependent polarizability. Approximate values of the polarizability are obtained by an application of the equations-of-motion method. The entire calculation is performed without the use of continuum basis functions. The calculated cross sections agree well with the observed values.
