C254000100010 INC-SPECT The lower-energy bombardment lasted 60 minutes with C254000100011 an average intensity of 9.3x10**13 particles/minute, C254000100012 while the higher-energy bombardment lasted for 108 C254000100013 minutes with an average intensity of 4.7x10**13 C254000100014 particles/ minute. C254000100015 DETECTOR (GELI) A Ge(Li) gamma-ray spectrometer. C254000100016 SAMPLE Isotopically pure 208Pb targets of thickness 42-45 C254000100017 mg/cm2. C254000100018 METHOD (ACTIV) 208Pb targets were irradiated with beams of C254000100019 48Ca ions of incident energy 300 and 410 MeV from the C254000100020 SuperHILAC of the Lawrence Berkeley Laboratory. C254000100021 Absolute cross sections were measured only in the C254000100022 higher-energy bombardment due to difficulties in C254000100023 determining the number of 48Ca ions passing through C254000100024 the target in the lower-energy irradiation. Following C254000100025 the bombardments the induced radioactivities in the C254000100026 target were detected with a gamma-ray spectrometer. C254000100027 ANALYSIS (DECAY) The decay of the observed activities was C254000100028 followed for a period of approximately two months. C254000100029 Specific radionuclides produced were identified on C254000100030 the basis of gamma-ray energy, half-life and relative C254000100031 abundance of associated gamma-rays. In this manner 94 C254000100032 and 109 radionuclides were identified in the low- and C254000100033 high-energy reactions, respectively. C254000100034 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties.
