Abstract
A quantum mechanical study of the vibrational relaxation in the collis ions of NO+ with He is reported. An ab initio potential energy surface has been computed using the coupled cluster singles-doubles approxima tion. Vibration relaxation cross-sections have been calculated on this surface by using the centrifugal sudden approximation. The correspond ing vibration relaxation rate coefficients are obtained for the temper ature range 100-1000 K. A comparison of the theoretical and experiment al results is discussed.
