Description
Summary:Links between two well known methods: methods of zero-range and non-overlapped (muffin-tin) potentials are discussed. Some difficulties of the method of zero-range potentials and its possible elimination are discussed. We argue that such advanced method of ZRP potential can be applied to realistic electron-molecular processes. The method reduces electron-molecule scattering to generalized eigenvalue problem for hermitian matrices and admit fast numerical scheme. A noteworthy feature of the method is direct possibility to calculate the wave functions (partial waves). The theory is applied to electron-uracil scattering. Partial phases and cross-sections at low energies are evaluated and plotted.
