The energy spread in the beams was of theD503400100009 order of 1 keV. D503400100010 SAMPLE For absolute resonance stregth measurements: D503400100011 The Ne tagets were prepared by driving 3 keV 22Ne ions D503400100012 into tantalum backings. D503400100013 METHOD (GSPEC) D503400100014 DETECTOR (GELI) An 80 cm**3 Ge(Li) at a distance of 1 to 5 cm D503400100015 from the target , at an angle of 55 degree wich respectD503400100016 to the proton beam was used to detect the gamma-rays. D503400100017 The detector resolution was 2.6 keV at 1.33 MeV and 10 D503400100018 keV at 10 MeV. D503400100019 (NAICR)The excitation curve of the reaction was D503400100020 measured using a cylindrical 10x10 cm NaI detector set D503400100021 at an angle of 55 degree wich respect to the proton D503400100022 beam and at a distance of 4 cm from the target. D503400100023 ANALYSIS In REACTIONs FCT=1/(2Jp+1)(2Jt+1), D503400100024 where is Jp = spin of incident projectile and D503400100025 Jt = spin of target nucleus. D503400100026 In the formula of resonance strength: D503400100027 g*Gamma(i)Gamma(j)/Gamma(tot) D503400100028 instead of usual statistical weight: D503400100029 g=(2J+1)/(2Jp+1)(2Jt+1), the authors used g=(2J+1) D503400100030 ERR-ANALYS (DATA-ERR) The error of 25% on the strengths is due to D503400100031 1) uncertainties in the areas of the resonance peaks, D503400100032 2) the relative efficiency of the NaI detector, D503400100033 3) the strength of the Ep=1280 keV resonance.
