The beam direction was O0608 1 13 perpendicular to the emulsion surface. O0608 1 14 COMMENT -By authors- We count as fission events only single O0608 1 15 tracks with range >= 17 um. O0608 1 16 SAMPLE Uranium, thorium, and bismuth were loaded into the O0608 1 17 emulsions. O0608 1 18 Comment by compiler: the authors mentioned 238U O0608 1 19 among the loaded nuclei. Most likely, 238 here means O0608 1 20 not the pure isotope but the average atomic mass for O0608 1 21 natural uranium loaded. O0608 1 22 CORRECTION Performed: Subtraction of background estimated from O0608 1 23 irradiation of unloaded emulsions. Correction to O0608 1 24 fissions produced by secondary particles, about 35%, O0608 1 25 with an uncertainty of 40%. O0608 1 26 MISC-COL (MISC) Number of observed fission events. O0608 1 27 ADD-RES (RANGE) Range distributions of the tracks. O0608 1 28 STATUS (TABLE) Tabl.I from Nuovo Cim.,27(1963)468 O0608 1 29 HISTORY (19980220C) AP: By Khlopin's Institute.
