State-to-state differential cross sections have been measured for scattering of NO({sup 2}{Pi}{sub 1/2},{ital j}=0.5) by Ar at kinetic energies of 117, 149, 442, and 1694 cm{sup {minus}1}. The differential cross sections at each collision energy are presented as a function of final state ({Omega}{prime},{ital j}{prime}) at constant center-of-mass scattering angle. Center-of-mass angular distributions are also given for final rotational states ({sup 2}{Pi}{sub 1/2}, {ital j}{prime}=1.5, 2.5, 8.5, 12.5, and 14.5) at a kinetic energy of 442 cm{sup {minus}1}, and for {ital j}{prime}=18.5 at a kinetic energy of 1694 cm{sup {minus}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. {bold 99}, 7725 (1993)] using newly calculated {ital ab} {ital initio} potential energy surfaces, and thus may serve as a new benchmark for the microscopic dynamics of molecular energy transfer in open-shell molecules. {copyright} {ital 1996 American Institute of Physics.}
