Angular distributions of photoelectrons from K-shells of a fixed-in-space CO molecule calculated by the multiple scattering Xα method

Angular distributions of photoelectrons from both C and O K-shells of a fixed-in-space CO molecule have been calculated using a continuum multiple scattering method with partially overlapping spheres. The calculations have been performed at several photon energies from the ionization thresholds up to about 30 eV above them, where the sigma* shape resonances occur. Comparison with recently published experimental results (Motoki S et al 2000 J Phys. B: At. Mol. Opt. Phys. 33 4193) shows that this simple method gives a rather reliable description of the most sophisticated experimental data.
