C189700100014 SAMPLE For the TRIUMF and LAMPF measurements the target was C189700100015 made of a thin bismuth layer (0.8-2 mg/cm ) C189700100016 evaporated onto thin aluminum backing. Due to the C189700100017 lower currents at IUCF, thick targets (10-45 mg/cm) C189700100018 had to be used. C189700100019 DETECTOR (SIBAR,GELI) C189700100020 METHOD (ACTIV,CHSEP,RCHEM,ASPEC,GSPEC) Two identical targets C189700100021 were irradiated at each proton energy. The first C189700100022 target was put aside for several hours to allow for C189700100023 the short-lived activities to decay. The radioisotope C189700100024 211At is in secular equilibrium with its decay C189700100025 product 211Po which emits a distinct high energy C189700100026 alpha (7.45 MeV). The yield of these alphas is C189700100027 directly related to the production rate of C189700100028 211At. The second target underwent chemical C189700100029 separation for astatine immediately after the C189700100030 irradiation. The chemically separated astatine C189700100031 activities were determined by simultaneous alpha and C189700100032 gamma counting. Whenever possible, measurements were C189700100033 carried out by both systems and the degree of C189700100034 agreement was used to determined the reliability of C189700100035 the two systems. C189700100036 ANALYSIS (PGS,INTED) All gamma spectra were analyzed with C189700100037 GAMANAL program, and alpha spectra were integrated by C189700100038 hand. To determine cross sections, authors first C189700100039 calculated the effective cross section sigma(211At) C189700100040 for the production of 211At from the yield in the C189700100041 direct target; then multiplied this effective cross C189700100042 section by the ratio of yields 210-xAt/211At in the C189700100043 chemically separated target of the same thickness.
