Total interaction cross sections have been measured for 8 Li on C and Pb targets, for 9 Li on C, Al, Cu, Sn and Pb targets, as well as for 11 Li on C, Sn and Pb targets at about 80 MeV/nucleon. In addition, 2n-removal cross sections for 11 Li have been extracted. These measurements are used to determine the nuclear and the electromagnetic part of the cross sections for the different projectile-target combinations. The experimental results are compared to different model calculations. These comparisons allow one to draw conclusions on the matter density distribution of the neutron-rich lithium isotope 11 Li. By comparing our data on the electromagnetic dissociation of 11 Li with all the other data available in the literature, we are able to put constraints on the dipole-strength distribution in 11 Li.

Measurements of Interaction Cross-Sections and Nuclear Radii in the Light p Shell Region

Tanihata, I. ; Hamagaki, H. ; Hashimoto, O. ; et al.
Phys.Rev.Lett. 55 (1985) 2676-2679, 1985.

Interaction cross sections (σI) for all known Li isotopes (Li6-Li11) and Be7, Be9, and Be10 on targets Be, C, and Al have been measured at 790 MeV/nucleon. Root mean square radii of these isotopes as well as He isotopes have been deduced from the σI by a Glauber-type calculation. Appreciable differences of radii among isobars (He6-Li6, He8-Li8, and Li9-Be9) have been observed for the first time. The nucleus Li11 showed a remarkably large radius suggesting a large deformation or a long tail in the matter distribution.
