The algebraic-eikonal approach to vibrationally elastic scattering in the e-HCl collision

The algebraic-eikonal approach to the e-molecule collision process has been applied to the calculation of the e-HCl vibrationally elastic scattering cross section in the energy range of the incoming electron 0.5<or=E<or=10.0 eV. Comparison is made with experimental results as well as with other theoretical approaches. The resonant behaviour of the cross section in this energy region is well reproduced by the present calculations.
