Abstract / Description:We use multiple scattering in non spherical potentials (MSNSP) to calculate the angular distributions of electrons photoemitted from the 1s shells of CO and N-2 gas phase molecules with fixed in space orientations. For low photoelectron kinetic energies (E < 50 eV) as appropriate to certain shape resonances the electron scattering must be represented by non spherical scattering potentials which are naturally included in our formalism. Our calculations accurately reproduce the experimental angular patterns recently measured by several groups including those at the shape resonance energies. The MSNSP theory is thus an efficient method to calculate the scattering states of low energy electrons in small low symmetry systems.
