D037000100011 Different processes following the breakup should be D037000100012 considered: elastic breakup (EBU), when neither of the D037000100013 breakup fragments is captured by the target; D037000100014 incomplete fusion reaction (ICF), when one of the D037000100015 fragments is captured by the target; and complete D037000100016 fusion following breakup (CFBU), when all breakup D037000100017 fragments are captured by the target. D037000100018 The sum of complete fusion (including two body D037000100019 fusion and complete fusion following breakup) and D037000100020 incomplete fusion is called total fusion.
