Low-energy electron impact elastic and inelastic scattering from CF3I

Absolute differential cross sections for elastic scattering from CF3I are reported between 1.5 and 60 eV and over scattering angles of 20°–130°. Vibrational excitation cross sections for the composite stretching modes are shown to be preferentially enhanced at incident electron energies between 5 and 9 eV indicating the formation of short-lived shape resonances.
