ANGLE-RESOLVED AUGER SPECTRUM OF THE N-2 MOLECULE

Angle-resolved Auger electron spectra of N-2 have been measured with g ood statistics at photon energies corresponding to the pi resonance a nd the sigma shape resonance, below and above the N 1s threshold, res pectively. Angular anisotropy is observed in both cases, but disappear s as expected far above threshold. Satellite Anger transitions also sh ow some angular anisotropy close to the N 1s threshold. This is attrib uted to the creation and decay of conjugate shakeup initial states, wh ich have non-ground-state symmetry.
