D407700100021 The energy degradation was calculated using the tables D407700100022 of Williamson et al.,Report, CEA-R-3042 (1966) and D407700100023 Tobailem et al., Report CEA-N-1466(1) (1971). D407700100024 No detail was given for the energy scale uncertainties.D407700100025 SAMPLE The target material were thin Al foils, nitrogen and D407700100026 neon gas. D407700100027 Al and Ti foils were used for monitoring the beam. D407700100028 Al and Ag foils were used for cell windows. D407700100029 METHOD (ACTIV,STTA,GSPEC,CHSEP) Stacks of Al foils were D407700100030 irradiated for 70 to 240 minutes with 1 to 1.5 uA D407700100031 He-3 beam. D407700100032 The gases were irradiated in stainless steel D407700100033 cylindrical gas cells having Al and Ag windows for D407700100034 95 to 160 min and the beam current was 200 to 500 nA.D407700100035 Thin-walled Al cylinders were used as inner liner to D407700100036 help the removal of the Be-7 from the stainless D407700100037 steel cells. D407700100038 Max four cells were placed in one Stack. D407700100039 The irradiation were done on air. D407700100040 Be-carrier added chemical separation was applied to D407700100041 separate the produced Be-7. D407700100042 Standard high resolution gamma-ray spectroscopy was D407700100043 used to Determine the activity. D407700100044 The contribution of Be-7 produced in the Al windows D407700100045 was substracted. D407700100046 Control irradiation were performed using silver D407700100047 windows on the gas cells. D407700100048 DETECTOR (HPGE,GELI) D407700100049 ANALYSIS Normal high resolution gamma-spectrometry was applied. D407700100050 Counting periods between two hours and seven days were D407700100051 applied.
