Electron-atom scattering using time-dependent density-functional theory

We present a method to obtain single-channel elastic electron-atom scattering phase shifts from time-dependent density functional theory (TDDFT). The system is placed in a spherical box, and TDDFT is used to calculate its discrete spectrum, from which phase shifts are deduced. The influence of ground state Kohn-Sham potentials and exchange-correlation kernels on the results are discussed.
