Scattering of state selected OH and NO — •Moritz Kirste, Xingan Wang, Hans Christian Schewe, Gerard Meijer, and Sebastiaan van de Meerakker — Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Deutschland
The crossed molecular beam technique is a mature and important experimental method to understand molecular interactions and molecular reaction dynamics. The Stark deceleration technique yields unprecedented control over both the internal and external degrees of freedom of polar molecules in a molecular beam. The combination of both techniques offers new possibilities in scattering experiments. In particular, crossed Stark-decelerated molecular beams allow detailed molecular scattering studies as a function of the collision energy, from low to high collision energies, and with a very high energy resolution. Recently, a new Stark decelerator molecular beam machine has become operational in our laboratory that is dedicated to crossed beam scattering experiments. We will discuss our results on the inelastic scattering of fully state selected OH(X2Π3/2,J=3/2,f) radicals with hexapole state-selected NO(X2Π1/2,J=1/2,f), as a function of the collision energy.
