SAMPLE     The U308 plaque (450 g).                               14802001    9 
DETECTOR   (IOCH) The boron chamber.                              14802001   10 
METHOD     First the number of delayed neutrons from the U30s     14802001   11 
           plaque, detected by the boron chamber immediately      14802001   12 
           after the irradiation, was measured. The number of     14802001   13 
           fissions per second from a known amount of uranium in  14802001   14 
           a second detection chamber was then determined under   14802001   15 
           the same geometrical conditions. The ratio of the      14802001   16 
           initial number of delayed neutrons per second to the   14802001   17 
           total number of fissions per second produced in the    14802001   18 
           plaque was thus found to be 1:60. Measurements with    14802001   19 
           and without cadmium and boron around the uranium       14802001   20 
           during irradiation showed that under these conditions  14802001   21 
           the effect is produced primarily by slow neutrons and  14802001   22 
           approximately follows the 1/v law.                     14802001   23
