The resulting resonance has $^{4}\\Sigma^{-}$ symmetry;\nthe higher vibrational levels of this resonance state coincide with, or are\nnearly coincident with, levels of the parent $a^{3}\\Pi$ state. Collisional\nrelaxation to the lowest vibrational levels in hot plasma situations might\nyield the possibility of a long-lived CO$^-$ state.",
