7Be,8B+208Pb Elastic Scattering at Intermediate Energies, J. Wang, Institute of Modern Physics, Chinese Academy of Sciences, P. R. China − The experiment of measuring elastic scattering angular distribution of 7Be, 8B on 208Pb target was carried out at Radioactive Ion Beam Line at Lanzhou (RIBLL) at center-of-mass energies of 121MeV and 164MeV respectively. As opposed to the situation for neutron halo nuclei 6He and 11Be (A. Di Pietro et al., PRL 105, 022701(2010)), for which the Coulomb Nuclear Interference Peak (CNIP) are obviously suppressed comparing to the stable nuclei, the CNIP for 8B is not suppressed and is a little higher than that for 7Be. The optic model fitting are done with the FRESCO code and the total reaction cross sections and fusion cross sections are deduced. The shallow depth of imaginary part of the optical potential are needed in order to fit the CNIP for 8B. It indicates that the 8B is easy to breakup. The deduced total reaction cross section for 8B is also larger than that for 7Be. The CCDC calculations are also performed for 7Be and 8B. The calculations reproduce the angular distribution very well for 7Be, but not for 8B. This unusual behavior of the elastic scattering cross section in the CNIP region for 8B comparing to the neutron halo nuclei could be due to the difference of structure between the proton halo (charged halo) and neutron halo (uncharged halo).
