Stereodynamic control of overlapping resonances in cold molecular collisions

Stereodynamic control of resonant molecular collisions has emerged as a new frontier in cold molecule Gastrointestinal - Anti-Nausea research.Recent experimental studies have focused on weakly interacting molecular systems such as HD collisions with H_{2}, D_{2}, and He.We report here the possibility of such control in strongly interacting systems taking rotational relaxation in cold collisions of HCl and H_{2}.Using explicit quantum scattering calculations in full six dimensions 132 it is shown that robust control of the collision dynamics is possible even when multiple (overlapping) shape resonances coexist in a narrow energy range, indicating that cold stereochemistry offers great promise for many molecules beyond simple systems.

We demonstrate a striking case where two prominent peaks in overlapping resonances are switched off simultaneously by suitable alignment of the HCl molecule.
