Asymmetry parameter β<sup>2</sup> for photoionization of helium leaving the He<sup>+</sup> ion in the n=2 level and differential cross sections(DCSs) in the n=2,3,4 levels with photon emission angle θ=90° are provided at photon energies 69-76.8 eV employing the R-matrix method with a 20-term target representation, in which five polarization orbitals 6̅l are included. The asymmetry parameter β<sub>2</sub> and the DCS, in the n=2 level in the region of 69-73 eV, are in good agreement with available experimental and theoretical results. Above the n=3 threshold, we present new theoretical results along with measurements. No theoretical and experimental results can be used to compare with the present calculations of the DCSs for photoionization into the He<sup>+</sup> ion in the n=3,4 levels. |
