Abstract
Calculations of intermediate energy electron scattering from the ground state of the potassium atom are performed using the unitarized distorted wave Born approximation. The target states (4s, 4p, 5s, 3d, 5p, 4d) of the potassium atom are calculated with a semi-empirical polarization potential added to the Hartree-Fock potential of the fixed core. Differential cross sections for elastic scattering and the 4s.Keywords
