Abstract
Continuum states of the CO+ cation are studied as a function of internuclear distances in the range 1.7-3.0 a(0). R-matrix wavefunctions are constructed for 1Sigma(+), (2)Pi, (2)Delta and 4Pi total symmetries by study of collisions of electrons with a CO2+ target. Complex quantum defects are obtained from above threshold energy scattering calculations, yielding resonance energy curves and corresponding electronic couplings to the CO+ continuum. Results are presented and discussed for the high-n Feshbach resonances of the CO+ spectrum converging to excited states of CO2+. These curves are responsible for the recently observed dissociative recombination of Co2+.
