Partial photoionization cross sections of four outer shells of N2
molecule are calculated in the random phase approximation in the energy
range from the first ionization threshold up to 70 eV. The zero order
orthonormal basis set of the Hartree-Fock wave functions is calculated
in prolate spheroidal coordinates. The results are in a good agreement
with the existing experimental data.
