D028100100014 METHOD The total fusion cross section has been measured at D028100100015 energies close and above the Coulomb barrier. D028100100016 Different processes following the breakup should be D028100100017 considered: elastic breakup (EBU), when neither of the D028100100018 breakup fragments is captured by the target; D028100100019 incomplete fusion reaction (ICF), when one of the D028100100020 fragments is captured by the target; and complete D028100100021 fusion following breakup (CFBU), when all breakup D028100100022 fragments are captured by the target. D028100100023 The sum of complete fusion (including two body D028100100024 fusion and complete fusion following breakup) and D028100100025 incomplete fusion is called total fusion.

D028100200004 METHOD (TOF) D028100200005 DETECTOR (MCPLT) Has been used as the start detector. D028100200006 (SIBAR) Passivated implanted planar silicon detector D028100200007 ERR-ANALYS (ERR-T) Total error. The normalization of the fusion D028100200008 cross sections was obtained by counting elastic D028100200009 scattering events in the spectra, when the experimentalD028100200010 conditions were such that the scattering was purely D028100200011 Rutherford. Otherwise, it was obtained using the D028100200012 integrated beam current in the Faraday cup and the D028100200013 nominal target thickness. In the first case, the D028100200014 associated uncertainty was around 2%, whereas in the D028100200015 latter it was the sum of three contributions: D028100200016 around 2% from the integrated beam current, 10% from D028100200017 the target thickness, and 1% from the solid angle D028100200018 detection system determination.
