D421000100018 The energy of the primary beam was obtained from D421000100019 cyclotron settings, calibrated in a separate D421000100020 experiment. D421000100021 Four gascells were stacked in a closed metal cylinder D421000100022 serving as a holder and Faraday-cup for the D421000100023 preliminary beam current measurement. D421000100024 The produced activities were assessed nondestructively D421000100025 i.e. the irradiated cells were placed without any D421000100026 treatment at large sample-detector distances. D421000100027 The first measurements were done immediately after D421000100028 the end of bombardment while the second set was D421000100029 started about 2 h later.

D421000100041 DECAY-DATA Decay data were taken from NuDat database. D421000100042 ERR-ANALYS (EN-ERR) The uncertainty on the particle energy was D421000100043 estimated taking into account the uncertainties on the D421000100044 energy of the primary beam, the uncertainty on the D421000100045 thicknesses of the different stopping media in the D421000100046 stack, the fluctuations of the gas target density and D421000100047 the energy straggling. The uncertainty on the energy D421000100048 varies between 0.3 and 1.0 MeV. D421000100049 (ERR-T) The uncertainties were estimated in the D421000100050 standard way: the independent relative errors of the D421000100051 linearly contributing processes: D421000100052 * number of the bombarding particles, D421000100053 * number of the target nuclei, D421000100054 * decay data, D421000100055 * detector efficiency and D421000100056 * peak area) D421000100057 were summed quadratically and the square root of the D421000100058 sum was taken. The uncertainties on the absolute cross D421000100059 sections were estimated to be 12-20%. D421000100060 ADD-RES (THEO) The measured experimental data were compared to D421000100061 and analyzed with theoretical calculations based on D421000100062 the model code ALICE-IPPE. D421000100063 (TTY-C) On the basis of the new experimental cross D421000100064 sections integral yields were calculated. D421000100065 STATUS (APRVD) S. Takacs, 2009.03.16.
