A0137001 9 INSTITUTE (1USALAS) A0137001 10 FACILITY (LINAC,1USALAS) A0137001 11 METHOD (STTA,ACTIV,EXTB) A0137001 12 SAMPLE Each packet contained a number of 1.268-cm diameter A0137001 13 monitor, target, and recoil-catcher foils. Elemental A0137001 14 Al, with a purity of 99.997% and thickness A0137001 15 26 um was used for beam monitors and forward A0137001 16 and backward recoil catchers. A catcher foil was A0137001 17 placed both upstream and downstream of each target A0137001 18 to determine recoil loss corrections, and monitors A0137001 19 were situated likewise to measure any loss of beam A0137001 20 intensity upon traversal of the experimental packet. A0137001 21 All Al monitors were, of course, fully compensated. A0137001 22 High-purity (>=99.9%) elemental targets of A0137001 23 La, Mo, and V were irradiated, and an entire packet A0137001 24 was sandwiched together and maintained at a constant A0137001 25 position in the proton beam with an external holder. A0137001 26 While each packet contained a single La and Mo foil, A0137001 27 three adjacent V targets were incorporated. In this A0137001 28 way, the cross sections for nuclides such as 24-Na, A0137001 29 22-Na, and 7-Be, which are also produced in and A0137001 30 recoil from the Al catchers, could be determined by A0137001 31 analyzing the central V target. A0137001 32 Two independent bombardments were performed. A0137001 33 In the first, the thickness of each of the targets was A0137001 34 approximately 0.05 mm, while in the second 0.25 mm A0137001 35 was typical. Such a procedure allowed the study of A0137001 36 individual cross sections as a function of target A0137001 37 thickness in order to correct for any possible A0137001 38 production via secondary reactions.
