title: Reaction and scattering in cold electron collisions.
abstract: Experimental data are presented for the scattering of electrons by CCl4 between 8 and 200 meV impact energy. These results are used in conjunction with data for the reactive process, yielding Cl-, to study the low energy behavior of a system which simultaneously displays both reactive and elastic scattering channels. Phase shifts are derived and illustrate how channel competition develops as the energy falls. This behavior and the involvement of vibronic effects at impact energies above approximately 30 meV pose a challenge to theory.
