DETECTOR   (PLATE) Low sensitivity K0 Ilford emulsion, about      O060800100011 
           400-um thick, were loaded with different               O060800100012 
           elements under study. 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
