Zusammenfassung
We present detailed calculations on resonances in rotationally and spin-orbit inelastic scattering of OH (X2Π, j = 3/2, F₁, f) radicals with He and Ne atoms. We calculate new ab initio potential energy surfaces for OH-He, and the cross sections derived from these surfaces compare well with the recent crossed beam scattering experiment of Kirste et al. [Phys. Rev. A 82, 042717 (2010)10.1103/PhysRevA.82.042717]. We identify both shape and Feshbach resonances in the integral and differential state-to-state scattering cross sections, and we discuss the prospects for experimentally observing scattering resonances using Stark decelerated beams of OH radicals.
