The optical potential of 6He in the eikonal approximation
Abstract The new data of the elastic scattering of 6 He+ 12 C at about 40 MeV/nucleon are analyzed in the eikonal approximation. The 6 He+ 12 C phase-shift function is evaluated completely without any ad hoc assumption by a Monte Carlo integration, which makes it possible to use a realistic 6-nucleon wave function for a halo nucleus 6 He. The effect of the breakup of 6 He on the elastic differential cross sections as well as the optical potential is studied at different energies from 40 to 800 MeV/nucleon.
Reaction cross sections for collisions involving exotic light nuclei within the glauber approach
The reaction cross sections for the interaction of exotic nuclei 6He and 11Li with 12C nuclei are calculated for energies of about 0.8 GeV per nucleon. The cross sections calculated by the exact Glauber formula are compared with their counterparts found by using the formulas of the optical limit, the rigidtarget approximation, and the few-body approximation. The effect of the structure of the nuclei being considered on the calculated cross sections is examined. The root-mean-square radii of the 6He and 11Li nuclei are estimated on the basis of experimental data on the cross sections for the interaction of these exotic nuclei with 12C nuclei.
