The loaded and unloadedO0607 1 13 pellicles were irradiated as stacks. Each stack O0607 1 14 consisted of 3 400-mumeter-thick pellicles, with each O0607 1 15 pellicle loaded with a different element. The beam O0607 1 16 direction was perpendicular to the stack surface for O0607 1 17 the fission cross section measurements. O0607 1 18 (IOCH) The ionization chamber was used for relative O0607 1 19 monitoring of the proton beam. O0607 1 20 SAMPLE Natural silver was a constituent of the emulsion. O0607 1 21 Uranium, thorium, bismuth and tungsten were loaded intoO0607 1 22 the emulsion pellicles. O0607 1 23 Comment by Compiler: the authors mentioned 238-U and O0607 1 24 184-W among the loaded nuclei. O0607 1 25 Most likely, 238 and 184 here mean not the pure O0607 1 26 isotopes but the average atomic mass for natural O0607 1 27 uranium and tungsten loaded.

O0607 1 39 ERR-ANALYS (ERR-1) The uncertainty in the relative beam monitoringO0607 1 40 used for comparisons between different exposures. O0607 1 41 Indeed, this error on absolute proton flux at the stackO0607 1 42 location was estimated to be of the order of a factor O0607 1 43 2, so that we could not rely on it for absolute cross O0607 1 44 section measurements. - Comment by authors - O0607 1 45 (ERR-2) The uncertainty in the number of loaded nuclei O0607 1 46 comment by compiler: this uncertainty may be O0607 1 47 underestimated by authors.
