Abstract
Cross sections were measured for fragments (4<Z<27) from the 5.0,6.2,6.9,8.0,10.2 and 12.7 MeV/N63Cu+12C reactions. Excitation functions were constructed for each Z value, and a nearly complete set of mass-asymmetric barriers has been obtained for75Br. There is excellent agreement between the experimentally determined barriers and the finite-range model calculations, while there is strong disagreement with the liquid-drop model calculations.
