D419400100010 FACILITY (VDG,3HUNDEB) D419400100011 (CYCLO,3HUNDEB) D419400100012 SAMPLE Targets were made by evaporating natural metallic Ge D419400100013 on thin, high purity Al foils. D419400100014 The thickness of the targets varied between 50 and 290 D419400100015 ug/cm2, corresponding to a proton energy loss of D419400100016 ~2 keV at Ep=4.4 MeV and ~25 keV at Ep=1.6 MeV, D419400100017 respectively. D419400100018 METHOD (SITA,ACTIV,EXTB,GSPEC) D419400100019 Rutherford backscattering (RBS) was used to monitor D419400100020 the target stability with a surface barrier detector D419400100021 at 150 degree. D419400100022 Faraday cup was used to collect the charge using a D419400100023 proton beam current less than 500 nA. D419400100024 Secondary electron suppression was used with -300 V. D419400100025 Irradiation lasted between 3 and 11 h. D419400100026 Measurements started 0.5 h after end of irradiations. D419400100027 The energy loss was calculated using the SRIM code. D419400100028 Cross sections and astrophysical S factor were derived D419400100029 from the primary data. D419400100030 Reaction Rates were calculated from the measured data.
