Stereodynamical control of cold collisions between two aligned D2 molecules
Abstract
Resonant scattering of optically state-prepared and aligned molecules in the cold regime allows the most detailed interrogation and control of bimolecular collisions. This technique has recently been applied to collisions of two aligned ortho-D2 molecules prepared in the j=2 rotational level of the v=2 vibrational manifold using the Stark-induced adiabatic Raman passage technique. Here, we develop the theoretical formalism for collisions of two aligned molecules and apply our approach to state-prepared D2(v=2,j=2) + D2(v=2,j=2) --> D2(v=2,j=2) + D2(v=2,j=0) collisions. Quantum scattering calculations were performed in full-dimensionality on an accurate H-H interaction potential. Key features of the experimental angular distributions are reproduced and attributed primarily to a partial wave resonance with orbital angular momentum L=4
