We report fully-quantum, coupled-state ( CS) calculations of inelastic integral cross sections for collisions of NO((2)Pi) with He. The scattering calculations, which take into account the. ne structure of the NO radical, were done on a grid of collision energies large enough to ensure converged state-to-state rate coefficients for temperatures ranging from 1 K up to 350 K.
