Abstract

Phaseshifts, partial and total cross sections for elastic electron scattering by small sodium clusters are calculated. The non-local dynamic interaction of the extra electron with the neutral cluster is described within the many-body framework of Dyson's equation. Low-energy electron scattering resonances and the energies of bound and quasibound states are shown to be very sensitive to the non-local exchange and dynamic polarization interactions.
