We Report Cross Sections For The Collision Of
O(3p) + Co2 Scattering At Collision Energies Which
Are Important To Understand The O Escape From Mars
Atmosphere. The Cross Sections Were Calculated Using
Newly Developed State-Of-The-Art Ab Initio Potential
Energy Surfaces (Pess) Correlating The Lowest Energy
Asymptote Of The Complex.

Cross-Sections Of O(3p)-Co2 Compared To That Of The
Rigid Rotor Approximation Previously Reported [1].
This Also Allows For An Understanding Of Rotational
And Vibrational Energy Transfer Processes In This
Atom-Triatom Collision.
