Clear experimental evidence for p-wave attachment-threshold behavior in electron attachment to chlorine molecules.
Using the laser photoelectron attachment method and chlorine molecules in a seeded supersonic beam, we have measured the energy dependence of the cross section for dissociative electron attachment (DA; Cl- formation) over the range 0-195 meV with an energy width of about 1 meV. Our data provide the first clear experimental evidence for p-wave behavior of a DA cross section near zero energy and are in good overall agreement with recent theoretical predictions.
