A068300100011 (3CPRAEP) A068300100012 FACILITY (VDGT,2GERLMU) The experiment was done with the 9-Be A068300100013 beam. A068300100014 METHOD (ACTIV) A068300100015 (ASSOP) The cross sections were deduced by the in-beam A068300100016 observation of the alpha-particles emitted in the A068300100017 ground state decay of the evaporation residues.

The complete 9-Be plus likely 8-Be fusion A068300200006 cross sections were calculated adding the 2N+P3N, A068300200007 3N and 4N channels and the fission taken from E1658. A068300200008 The results are in agreement with A0564 and A068300200009 consequently show the same discrepancy with E1658. ForA068300200010 This reason the fusion cross section were calculated asA068300200011 the weighted average of the data from the present A068300200012 experiment and from A0564. A068300200013 ERR-ANALYS (ERR-T) The overall accuracy of the cross sections is
