Using interaction potentials screened with the Debye‐Hückel length, the effects of plasma shielding on energy levels and electrons scattering from neutral and ionized caesium are estimated. Both energy levels and atomic scattering cross‐sections are found to be sensitive to the inclusion of screening. Relating to the scattering by the Cs + ion, a low‐energy resonance near E = 0.3 Ryd is found which arises from the f ‐wave phase shift and reflects the individual behaviour of the scattering ion.
