Reaction and proton-removal cross sections of Li6, Be7, B10, C9,10,11, N12, O13,15, and Ne17 on Si at 15 to 53 MeV/nucleon

Excitation functions for total reaction cross sections, σ_R, were measured for the light, mainly proton-rich nuclei Li6, Be7, B10, C9,10,11, N12, O13,15, and Ne17 incident on a Si telescope at energies between 15 and 53 MeV/nucleon. The telescope served as target, energy degrader and detector. Proton-removal cross sections, σ_2p for Ne17 and σ_p for most of the other projectiles, were also measured. The strong absorption model reproduces the A-dependence of σ_R, but not the detailed structure. Glauber multiple scattering theory and the Jeukenne, Lejeune, and Mahaux (JLM) folding model provided improved descriptions of the measured σ_R values. Rms radii, extracted from the measured σ_R using the optical limit of Glauber theory, are in good agreement with those obtained from high energy data. One-proton removal reactions are described using an extended Glauber model, incorporating second order noneikonal corrections, realistic single particle densities, and spectroscopic factors from shell model calculations.
