Notes:
State-to-state differential cross sections have been measured for scattering of NO(2Π1/2,j=0.5) by Ar at kinetic energies of 117, 149, 442, and 1694 cm−1. The differential cross sections at each collision energy are presented as a function of final state (Ω′,j′) at constant center-of-mass scattering angle. Center-of-mass angular distributions are also given for final rotational states (2Π1/2, j′=1.5, 2.5, 8.5, 12.5, and 14.5) at a kinetic energy of 442 cm−1, and for j′=18.5 at a kinetic energy of 1694 cm−1. Rotational rainbow structure is seen in both types of data. The results are generally in good agreement with quantum scattering calculations carried out by Alexander [J. Chem. Phys. 99, 7725 (1993)] using newly calculated ab initio potential energy surfaces, and thus may serve as a new benchmark for the microscopic dynamics of molecular energy transfer in open-shell molecules. © 1996 American Institute of Physics.
