N2 - The forward-backward asymmetry of photoelectron angular distributions produced in the vacuum ultraviolet photoionization of helium was measured. Off resonance, the energy dependence of this asymmetry is generally well represented by the RPAE calculations. In the region of the 2s2p 1P1 and 2P2 1D2 autoionizing resonances, these data allowed to extract the Fano resonance parameters for the quadrupole resonance. Furthermore, the strong energy dependence of the asymmetry permitted an experimental determination of the matrix element ratio and the relative continuum phase difference.
