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\phantom\rule0.3em0ex\ensuremathμK between 87Rb atoms in the 5S1∕2,F=1,mF=\ensuremath-1 and 5S1∕2,F=2,mF=1 states.
