Differential cross sections for rotationally inelastic collisions of NO(2Π1/2, j′⩽2.5) with NO(2Π1/2, j′⩽2.5) at a kinetic energy of 442 cm−1

This is the authors' abstract. We don't add key points for this paper.

We report crossed molecular beam measurements of state-resolved differential cross sections for NO+NO collisions at relative kinetic energy of 442 cm−1. The initial state (NO 2Π1/2v=0,j⩽2.5) was prepared in both beams by pulsed supersonic expansion of pure NO gas. Scattered products were detected by resonance enhanced two-photon ionization. NO product distributions were measured in both scattering angle and final rotational state. Intensity maxima were found in both types of scans, and comparable populations were found in both of the spin-orbit manifolds (2Π1/2 and 2Π3/2). The results obtained here are compared to previous NO+Ar scattering experiments and theory, NO dimer studies, and NO+NO bulb kinetics experiments.
