Abstract

The delayed x-ray detection technique was used to measure complete and incomplete fusion cross sections for the Be9+Sm144 reaction at sub- and near-barrier energies. Elastic and inelastic scattering for this system were also measured. Reaction cross sections were derived and the transfer cross sections of one neutron were calculated. The suppression of complete fusion above the barrier, of the order of 10%, is attributed to Be9 breakup and is considerably smaller than the value of 30% found for the Be9+Pb208 system.
