Title: Probing Quantum Scattering Resonances from Cold Collisions

Abstract:  At very low temperatures, approaching 1 K, the collision dynamics of interacting particles enters a regime dominated by quantum mechanics. As the de Broglie wavelength of particles becomes comparable to the interaction length between them, the possibility of tunneling through potential energy barriers becomes a possibility. As a consequence, short lived quasi-bound complexes may form between collision partners at particular collision energies, giving rise to resonance features in measured integral cross sections as a result of enhanced inelastic scattering from this complex.
