Crossed, pulsed molecular beam measurements of state-to-state differential cross sections have been carried out for scattering of NO({sup 2}{Pi}{sub 1/2}, {ital j}={lt}{ital cf}10;1;2{gt}) by Ar, at a kinetic energy of 442 cm{sup {minus}1}. Differential cross sections are presented (1) as functions of center-of-mass (c.m.) scattering angle for multiplet-conserving collisions {sup 2}{Pi}{sub 1/2}{r arrow}{sup 2}{Pi}{sub 1/2} and final states {ital j}{prime}=1.5, 12.5, and 14.5, and (2) as functions of final state {ital j}{prime} for both multiplet-conserving and multiplet-changing collisions {sup 2}{Pi}{sub 1/2}{r arrow}{sup 2}{Pi}{sub 3/2}, at a constant c.m. scattering angle of 50{degree}. Rotational rainbow structure is seen in both types of data. Some of the results are compared with the coupled-states calculations of Joswig, Andresen, and Schinke, J. Chem. Phys. {bold 85}, 1904 (1986).
