Density distribution of 8B studied via reaction cross sections Original Research Article

Reaction cross sections (σR) for 8B on Be, C and Al targets were measured at energies of 40A and 60A MeV. The density distribution of 8B was studied through a χ2-fitting procedure on the σR including the high-energy data using the optical limit of Glauber theory with assumptions on the enhancement of the σR at low energies. The result shows a long tail in the density distribution. Large one-proton removal cross sections were also observed to support the existence of a long proton tail consistent with its binding energy.
