O068800100008 DETECTOR (GLASD) The number of fissions was determined from O068800100009 the tracks left in glass by the fragments. The O068800100010 detection efficiency was obtained by means of a O068800100011 Pu-240 standard, and was (36 +- 1.5)% in the geometry O068800100012 used in the experiments. O068800100013 FACILITY (SYNCH,4ZZZDUB) O068800100014 METHOD (INTB) The layers and glass plates, together with an O068800100015 aluminum-plate monitor, were irradiated O068800100016 inside the vacuum chamber of the synchrotron. O068800100017 In calculation of the total number of fissions it was O068800100018 assumed that the angular distribution of the fragments O068800100019 can be represented as an expansion of cosines.
