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. S024900100041
