C234200100011 SAMPLE The Sc45 targets were prepared by evaporating C234200100012 scandium metal (stated purity 99.9%) upon aluminum C234200100013 backings. The scandium thickness was determined by C234200100014 microbalance weighing and varied from 0.482 to 0.925 C234200100015 mg/cm2. C234200100016 DETECTOR (NAICR,GELI) A 3x3-in. NaI(Tl) crystal scintillator, C234200100017 coupled with a 256-channel analyzer, was used for gammaC234200100018 counting. The absolute disintegration rates were C234200100019 determined using the photopeak efficiencies of Heath. C234200100020 A low-efficiency high-resolution spectrum was taken C234200100021 on one sample using a Ge(Li) detector coupled with a C234200100022 1000-channel analyzer. C234200100023 METHOD (ACTIV,CHSEP) Upon completion of the bombardment, C234200100024 each target underwent preparation for counting. The C234200100025 reaction was very clean, requiring minimum chemical C234200100026 removal of undesirable activities. The scandium C234200100027 targets and aluminum backings were dissolved in 6-M C234200100028 hydrochloric acid. C234200100029 ERR-ANALYS (DATA-ERR) The error in the absolute cross sections C234200100030 for the separate states is estimated to be about 20%.
