Abstract
The vibrational excitation of the HCl molecule by slow electrons is investigated in the adiabatic approximation using semiphenomenological R-matrix theory. The R matrix is extracted from the results of e-HCl scattering calculations of Padial, Norcross and Collins (1983) and from the results of HCl- bound-state calculations. The qualitative behaviour of the poles of the fixed-nuclei S matrix and the effects of dipole and polarisation interactions are considered. The calculated cross sections are much less than experimental ones near threshold but are in good agreement with experiment in the region of the broad resonance (1<E<3.5 eV).Keywords
