    Abstract

    The contribution of the dipole and non-dipole terms to the angular distribution of the photoelectrons from the N K shell of randomly oriented N2 molecules has been measured up to 80 eV above the N 1s threshold. The results are compared with all the previous experimental data and theoretical results. Consistently with the predictions of calculations performed in the frame of density functional theory (Toffoli and Decleva 2006 J. Phys. B: At. Mol. Opt. Phys. 39 2681) and in the random phase approximation (Hosaka et al 2006 J. Phys. B: At. Mol. Opt. Phys. 39 L25) the present data show that the non-dipole effects are rather small in the region investigated.
