摘要：

Reaction cross sections (sigma(R)) for B-8 on Be, C and Al targets were measured at energies of 40A and 60A MeV. The density distribution of B-8 was Studied through a chi(2)-fitting procedure on the sigma(R) including the high-energy data using the optical limit of Glauber theory with assumptions on the enhancement of the sigma(R) 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.
