Scattering of Stark-decelerated OH radicals with rare-gas atoms

摘要: We present a combined experimental and theoretical study on the rotationally inelastic scattering of OH ($X\,^2\Pi_{3/2}, J=3/2, f$) radicals with collision partners He, Ne, Ar, Kr, Xe, D$_2$ as function energy between $\sim 70$ cm$^{-1}$ 400~cm$^{-1}$. The are state selected velocity tuned prior to using Stark decelerator, field-free parity-resolved state-to-state relative cross sections measured in crossed molecular beam configuration. For all OH-rare gas atom systems excellent agreement is obtained predicted by close-coupling calculations based accurate \emph{ab initio} potential surfaces. This series experiments complements recent studies Xe [Gilijamse \emph{et al.}, Science {\bf 313}, 1617 (2006)], Ar [Scharfenberg Phys. Chem. 12}, 10660 (2010)], [Kirste Rev. A 82}, 042717 (2010)]. comparison for this set reveals interesting trends behavior.
