The investigation of light-ion induced direct reactions in inverse kinematics, using stored and cooled radioactive beams interacting with internal H, He, etc. gas-jet targets, bears a large potential for nuclear structure and astrophysics studies on exotic nuclei. The corresponding research project EXL (EXotic nuclei studied in Light-ion induced reactions at the NESR storage ring) has been accepted for the future facility FAIR. In order to explore the experimental conditions for measurements planned at FAIR and for proving the feasibility of the setup a first test experiment with an EXL prototype setup was performed at the Experimental Storage Ring (ESR) at GSI . Elastic, inelastic and other reaction channels were investigated with a stable 136Xe beam interacting with an internal hydrogen target. Results of the experiment will be presented and discussed.
