The loaded and unloadedO060700100013 pellicles were irradiated as stacks. Each stack O060700100014 consisted of 3 400-mumeter-thick pellicles, with each O060700100015 pellicle loaded with a different element. The beam O060700100016 direction was perpendicular to the stack surface for O060700100017 the fission cross section measurements. O060700100018 (IOCH) The ionization chamber was used for relative O060700100019 monitoring of the proton beam. O060700100020 SAMPLE Natural silver was a constituent of the emulsion. O060700100021 Uranium, thorium, bismuth and tungsten were loaded intoO060700100022 the emulsion pellicles. O060700100023 Comment by Compiler: the authors mentioned 238-U and O060700100024 184-W among the loaded nuclei. O060700100025 Most likely, 238 and 184 here mean not the pure O060700100026 isotopes but the average atomic mass for natural O060700100027 uranium and tungsten loaded.
