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