This is also a part of the commissioning of double side silicon strip detectors with a new type of ASIC based electronics which reduces the number of electronics channels necessary of one order of magnitude. The choice of the system was also motivated to get complementary information for our studies with the 17F loosely bound (Sp = 601 keV) at our LNL beam line dedicated to RIB in flight production (Eur.Phys.J ST 150(2007)47). The system demonstrated an energy resolution <80 keV with 5.5 MeV alpha sources and ΔE/E=1.2 % for 17O scattered beam. The quasi elastic reaction cross sections evaluated from the scattering data were the following: σ(mb) 235, 452, 590, 694, 779, 869 respectively at the energies (MeV) 42.5, 45.0, 50.0, 52.5, 55.0. The comparison of these data with the results for “similar systems” 17F+58Ni (Phys.Rev.C82(2010)054604)), 16O+58Ni (Nucl.Phys.A582(1995)314)), 8B+58Ni (Phys.Rev. C79(2009)021601(R)) suggest a small influence of the breakup process into the reaction mechanism at the barrier for the RIB 17F.  See the comparison in the enclosed figure.
