SUPER ELASTIC ELECTRON SCATTERING FROM POTASSIUM K.A. Stockman, V. Karaganov, I. Bray and P.J.O. Teubner Department of Physics, The Flinders University of South Australia, GPO Box 2100, Adelaide, South Australia, 5001, Australia Complete sets of spin averaged parameters, including the three Stokes parameters and differential cross sections, are presented at electron energies of 4, 10 and 54.4 eV for the 4P excited state in potassium. The four scattering parameters were determined using the superelastic scattering technique and cover an angular range from 0 to 150 degrees.
