Resonances in rotationally inelastic scattering of OH(X2π) with helium and neon

摘要

We present detailed calculations on resonances in rotationally and spin-orbit inelastic scattering of OH (X 2, 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)]. We identify both shape and Feshbach resonances in the integral and differential state-tostate scattering cross sections, and we discuss the prospects for experimentally observing scattering resonances using Stark decelerated beams of OH radicals.
