Differential cross sections for the elastic scattering of the electrons by H<sub>2</sub> at 100 and 150 eV have been calculated and compared with experiments. We use the momentum space method in which the electron–molecule system has a single centre and the effect of higher reaction channels on electron–molecule elastic scattering is approximated by an ab initio equivalent-local potential. It is added to the exact static-exchange potential for e–H<sub>2</sub> scattering. \pacs{34.80.Bm
