• We report on a new experimental setup for the investigation of proton induced reactions on exotic nuclei in inverse kinematics. It was installed and successfully used in the scattering study of intermediate-energy protons ( ∼ 700 MeV / u ) on neutron-rich nuclei 6,8He produced with the FRagment Separator (FRS) at the GSI facility, Darmstadt. A new pure liquid-hydrogen target was successfully adapted allowing to obtain low-background data as compared to commonly used (CH 2) n targets. Absolute differential cross-sections for elastic (p, 6,8He) scattering were obtained at angles corresponding to 0.05 ⩽ | t | ⩽ 0.125 (GeV/ c) 2 of the four-momentum transfer squared (− t) leading to the first diffraction minimum and spanning more than two orders of magnitude. They complement an earlier measurement at smaller angles 0.0025 ⩽ | t | ⩽ 0.05 (GeV/ c) 2 performed at the same energy with an active target. Both data sets agree well in the overlap region t ≈ 0.05 (GeV/ c) 2 and enable a refined and comparative study of the radial distribution of the nuclear matter density.
