Trapping cold molecules in an aperture: Effect of internal structure on particle transmission through an opening — •Piroska Dömötör1, Emerson Sadurni1, Bruce W.

Classically, rigid objects with elongated shapes can fit through apertures only when properly aligned. Quantum mechanical particles which have internal structure (e.g. diatomic molecules) are also affected during attempts to pass through small apertures, however there are interesting differences to classical structured particles. We illustrate here some of these phenomena for ultra-slow particles.
