Abstract

The relative photoionization cross section of atomic nitrogen across the 2s2p3(5S(o))np(4P(e)) autoionizing states and the beta parameter over the 2s -- > 3p and 4p resonances are measured using synchrotron-radiation-based photoelectron spectrometry. Results are compared with a multiconfiguration Hartree-Fock calculation. Resonance energies for autoionizing states from n = 3-10 are presented and compared with an earlier experiment. Values of the line-shape parameters GAMMA, q, and rho2 and discrete oscillator strengths f for the 3p, 4p, and 5p resonances are reported.
