D422500100011 Interspersed with aluminum foils as energy degraders D422500100012 and monitors. D422500100013 METHOD (STTA,ACTIV,EXTB,GSPEC) D422500100014 Primary energy of alpha-beam: 70-75 MeV, D422500100015 beam current: 200-250 nA. D422500100016 The beam spot on the foil stack was restricted to 5 mm D422500100017 by a central hole in a tantalum collimator. D422500100018 A Faraday cup was used for flux determination. D422500100019 DETECTOR (GELI) 95 cm3, coaxial, high-resolution D422500100020 (HPGE) 50 cm3 D422500100021 The energy calibration and relative detector efficiencyD422500100022 were calculated from the 152Eu standard spectra. D422500100023 MONITOR (13-AL-27(P,X)11-NA-24,,SIG) D422500100024 MONIT-REF (B0174002,H.J.Probst+,J,ARI,27,431,1976) D422500100025 REL-REF (N,,C.F.Williamson+,R,CEA-R-3042,1966) D422500100026 The energy of the alpha-particles after they had D422500100027 traversed half the thickness of each foil was computed D422500100028 from the range energy tables of this ref. D422500100029 ERR-ANALYS The total error in the experimental cross-section D422500100030 is contributed by D422500100031 (i) 1-4% error in the photopeak areas of D422500100032 characteristic gamma-rays, D422500100033 (ii) 1-8% error in their absolute abundances, D422500100034 (iii) 3% error in the photopeak efficiency of D422500100035 gamma-rays, D422500100036 (iv) 1-2% error due to the nonuniformity of the foil D422500100037 thickness and D422500100038 (v) 6% error in the standard monitor reaction D422500100039 cross-section assumed in the flux determination. D422500100040 The overall projected error is thus between 8-12% for D422500100041 various reactions. D422500100042 ADD-RES (THEO) The experimental data were compared to the D422500100043 results of the theoretical model code ALICE/85/300 D422500100044 (pre-equilibrium hybrid model) and index model. D422500100045 (COMP) The measured experimental data were compared to D422500100046 those found in the literature.
