Abstract

Direct measurements of the total fusion cross section for B-8+Ar-40 were achieved with the active target technique. The fusion excitation function was extracted at energies near the Coulomb barrier. The cross section is well described by a coupled reaction channels calculation. The data were compared with previous B-8 fusion experiments on Si-28 and Ni-58 targets. No evidence of striking enhancement of the total fusion cross section at near the Coulomb barrier, that was previously reported for the B-8+Ni-58 system, was observed in these direct measurements. The present data are systematically consistent with the results for B-8+Si-28 at higher energies with other weakly-bound systems at near-barrier energies. (C) 2021 The Author(s).
