Reaction cross sections at intermediate energies and Fermi-motion effect

This is the authors' abstract. We don't add key points for this paper.

Precise measurements of the reaction cross sections (σR) for ¹²C on Be, C, and Al targets and ¹¹Be on Be targets were performed in the energy range between 30 and 400 MeV/nucleon. The energy dependencies of σR for ¹²C, ¹¹Be, and ⁸B were compared to Glauber-type calculations performed using reliable nucleon-density distributions that are supported by experimental data. It was found that the Glauber-type calculations, which include the higher-order multiple scattering effect, the finite-range effect, and the Fermi-motion effect of nucleons in the nucleus, seem to provide a good prescription relating σR at intermediate energies to a proper nucleon-density distribution. This method provides a powerful tool with which to study the nuclear surface structure through the σR measurements.
