Small-angle proton elastic scattering on the 7,9,10,11,12,14Be and 8B nuclei at energies near 700 MeV/u was studied in inverse kinematics using secondary beams from the fragment separator FRS at GSI, Darmstadt. The hydrogen-filled ionization chamber IKAR served simultaneously as target and recoil proton detector. Projectile tracks measured with multiwire proportional chambers and the ALADIN magnet with a scintillator wall behind served for the separation of elastic scattering events. The obtained differential cross sections will allow to test various theoretical model calculations on the structure of the neutron- and proton-rich (halo) nuclei investigated.
In this presentation the experimental setup will be described and the procedure of the data analysis will be displayed. The data analysis is presently in progress. Preliminary results will be presented.
