摘要
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 (similar to 700 MeV/u) on neutron-rich nuclei (6.8)He 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, (6.8)He) scattering were obtained at angles corresponding to 0.05 <= vertical bar t vertical bar <= 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 <= vertical bar t vertical bar <= 0.05 (GeV/c)(2) performed at the same energy with an active target. Both data sets agree well in the overlap region t approximate to 0.05 (GeV/c)(2) and enable a refined and comparative study of the radial distribution of the nuclear matter density.
