The angular distributions of photoelectrons ejected from O and C
K-shells of fixed-in-space CO molecules were measured at several photon
energies for the cases of light polarization parallel and perpendicular
to the molecular axis. The results of measurements are in a reasonably
good agreement with the angular distributions calculated in the relaxed
core Hartree-Fock approximation.
