Momentum-resolved scattering experiments with laser-cooled atomic targetshave been performed since almost two decades with MOTRIMS (Magneto-Optical TrapRecoil Ion Momentum Spectroscopy) setups. Compared to experiments with gas-jettargets, MOTRIMS features significantly lower target temperatures allowing foran excellent recoil ion momentum resolution. However, the coincident andmomentum-resolved detection of electrons was long rendered impossible due toincompatible magnetic field requirements. Here we report on a novelexperimental approach which is based on an all-optical $^6$Li atom trap that --in contrast to magneto-optical traps -- does not require magnetic fieldgradients in the trapping region. Atom temperatures of about 2 mK and numberdensities up to 10$^9$ cm$^{-3}$ make this trap ideally suited formomentum-resolved electron-ion coincidence experiments. The overallconfiguration of the new trap is very similar to conventional magneto-opticaltraps. It mainly requires small modifications of laser beam geometries andpolarization which makes it easily implementable in other existing MOTRIMSexperiments.
