  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.
