Abstract

The cold and ultracold collisions involving rotationally hot oxygen molecules were investigated using quantum-mechanical, coupled-channel, and effective-potential scattering formulations. The quenching rate coefficients were given for initial rotational levels near the dissociation threshold. All possible states of rotationally hot oxygen were quenched very rapidly during a collision with a buffer gas helium atom. It is found that the quenching efficiency is always dominated by pure rotational transitions.
