We present the theoretical He photoionization, cross sections from the ground and the {sup 1,3}S bound excited states using a B-spline based configuration-interaction procedure for continuum (CIC). The resonant structures associated with selected sp,2n{sup {plus_minus}} and 2pnd {sup 1,3}P autoionization series below the He{sup +} N=2 threshold will be expressed quantitatively in terms of their resonant energies, widths, and peak cross sections. Comparisons with earlier theoretical results and recent experimental measurement will be presented. The nonresonant spectra from the 1s2s {sup 1,3}S metastable states will also be reexamined.
