Comprehensive study of reaction mechanisms for the 9Be+144Sm system at near- and sub-barrier energies

The delayed x-ray detection technique was used to measure complete and incomplete fusion cross sections for the Be-9+Sm-144 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 Be-9 breakup and is considerably smaller than the value of 30% found for the Be-9+Pb-208 system.
