Description
The proton-nucleus elastic scattering at intermediate energies is a well-established method of investigating the nuclear matter distribution in stable nuclei. When performed in inverse kinematics with radioactive beams, it can be applied to the investigation of unstable nuclei as well.
Recently, differential cross sections for small-angle proton elastic scattering on the 12,14Be [1], 8B [2] and 14-17C [3] nuclei were measured in inverse kinematics using secondary radioactive beams with energies near 700 MeV per nucleon produced with the fragment separator FRS at GSI, Darmstadt. The main part of the experimental setup was the active target IKAR, which was used for recoil protons detection. Auxiliary detectors for projectile tracking and isotope identification completed the setup. The measured differential cross sections were analyzed using the Glauber multiple scattering theory. For the evaluation of the data several phenomenological nuclear matter density parametrizations were used. The nuclear matter radii and radial density distributions were deduced. Extended nuclear matter density distributions were observed in 12,14Be isotopes and halo structure of 14Be was confirmed. Proton halo structure was observed for 8B. A possible neutron halo structure in 15,16C and 17C is discussed.
