S024900100016 INC-SOURCE A 9Be beam with an intensity of approximately 3.5 S024900100017 particle-nA was supplied by the sector-focusing S024900100018 cyclotron. S024900100019 SAMPLE A stack of 20 uranium targets, each of the target is S024900100020 composite of one uranium target and one self-support S024900100021 aluminum foil with about 0.3 mg/cm2 thickness. The S024900100022 uranium targets were prepared by molecular plating S024900100023 technique, uranyl nitrate onto the 0.8 mg/cm2 S024900100024 aluminum foil to a thickness of about 100 ug/cm2. S024900100025 DETECTOR (SI) The scattered beam particles were detected using S024900100026 four Si(Au) monitors positioned symmetrically with S024900100027 respect to the beam axis. After the irradiation, when S024900100028 events from short-lived fission products were S024900100029 substantially reduced, the alpha radioactivity of the S024900100030 long-lived 242Cm on Al catcher foils was measured by S024900100031 using silicon detectors placed in an off-line chamber. S024900100032 METHOD (ACTIV) After a delaying period of more than 80 d, in S024900100033 order to allow the short-living activity originating S024900100034 from the fission products to decay out, the alpha S024900100035 radioactivity of 242Cm on the catcher was measured in S024900100036 an off-line chamber. S024900100037 ERR-ANALYS (DATA-ERR) The cross section error included the S024900100038 number of alpha particles detected, the thickness of S024900100039 the uranium target, the geometry efficiency of the S024900100040 detector and the beam intensity in average.
