Title: Quantum scattering of distinguishable bosons using an ultracold-atom collider

Abstract

We describe an implementation of a magnetic collider for investigating cold collisions between ultracold atomic clouds in different spin states, and we use this to study scattering involving both even- and odd-order partial waves. Our method relies on the axial asymmetry of a double-well magnetic trap to selectively prepare the spin state in each cloud. We measure the energy dependence of s, p, and d partial-wave phase shifts in collisions up to 300 {mu}K between {sup 87}Rb atoms in the 5S{sub 1/2},F=1,m{sub F}=-1 and 5S{sub 1/2},F=2,m{sub F}=1 states.
