The beam direction was O060800100013 perpendicular to the emulsion surface. O060800100014 COMMENT -By authors- We count as fission events only single O060800100015 tracks with range >= 17 um. O060800100016 SAMPLE Uranium, thorium, and bismuth were loaded into the O060800100017 emulsions. O060800100018 Comment by compiler: the authors mentioned 238U O060800100019 among the loaded nuclei. Most likely, 238 here means O060800100020 not the pure isotope but the average atomic mass for O060800100021 natural uranium loaded. O060800100022 CORRECTION Performed: Subtraction of background estimated from O060800100023 irradiation of unloaded emulsions. Correction to O060800100024 fissions produced by secondary particles, about 35%, O060800100025 with an uncertainty of 40%. O060800100026 MISC-COL (MISC) Number of observed fission events.
