Description

The rate coefficient for the collisional relaxation of vibrationally excited O+2 ions by Kr decreases from 1.5 x 10-11 cm3 sec-1 at 300 K to a minimum of 9 x 10-12 cm3 sec-1 at kinetic energies, KEsub(cm) approx= 0.3 eV and increases to 6 x 10-11 cm3 sec-1 at 2 eV. The quenching at low KEsub(cm) (< 0.1 eV) is attributed to long range chemical attraction arising from chemical bonding of O+2 and Kr, while the quenching at higher kinetic energy is presumably due to short range repulsive forces.
