C254200100010 DETECTOR (GELI) Ge(Li) spectroscopy. C254200100011 METHOD (ACTIV,CHSEP) The target fragmentation products C254200100012 stopped in the target or catcher foils and the C254200100013 induced radioactivities were measured by gamma ray C254200100014 spectroscopy of the target foils and chemically C254200100015 separated gold fractions. These measurements were C254200100016 made on the sample at regular intervals over a period C254200100017 of from 30 min to one year after irradiation. The C254200100018 gamma ray emitting nuclei were identified using C254200100019 standard techniques and the production cross sections C254200100020 were calculated for those activities observed in the C254200100021 chemical samples were normalized to those seen in the C254200100022 unseparated foils. However, this normalization was C254200100023 not possible for the 25.2 GeV 12C data because only C254200100024 one foil was irradiated and chemically processed, and C254200100025 therefore these production cross sections are C254200100026 expressed in arbitrary units. C254200100027 ERR-ANALYS (DATA-ERR) The uncertainties given for sigma(Z,A) C254200100028 reflect the contribution from statistical C254200100029 uncertainties from the measurements and an ad hoc C254200100030 factor of 20% of the beta-decay feeding correction C254200100031 where applied.
