D034800100020 Different processes following the breakup should be D034800100021 considered: D034800100022 - Elastic breakup (EBU), D034800100023 when neither of the breakup fragments is captured D034800100024 by the target; D034800100025 - Incomplete fusion reaction (ICF), D034800100026 when one of the fragments is captured by the target; D034800100027 - Complete fusion following breakup (CFBU), D034800100028 when all breakup fragments are captured by the D034800100029 target. D034800100030 The sum of complete fusion (including two body fusion D034800100031 and complete fusion following breakup) and incomplete D034800100032 fusion is called total fusion.
