Abstract
Ultracold collisions between spin-polarized Na atoms and vibrationally excited Na2 molecules are investigated theoretically, using a reactive scattering formalism (including atom exchange). Calculations are carried out on both pairwise additive and nonadditive potential energy surfaces for the quartet electronic state. The Wigner threshold laws are followed for energies below 105 K. Vibrational relaxation processes dominate elastic processes for temperatures below 103–104 K. For temperatures below 105 K, the rate coefficients for vibrational relaxation (v 1 ! 0) are 4:8 1011 and 5:2 1010 cm3 s1 for the additive and nonadditive potentials, respectively. The large difference emphasizes the importance of using accurate potential energy surfaces for such calculations.
