DETECTOR   (IOCH) The methane-filled cloud chamber.               C2891001   13 
METHOD     (REC) The energy distribution of the neutrons was      C2891001   14 
           obtained by observing a large number of recoil         C2891001   15 
           protons in a cloud chamber. From the stopping power    C2891001   16 
           of the gas in the chamber and the range-velocity       C2891001   17 
           curve, the energy of the recoil protons was computed.  C2891001   18 
ANALYSIS   All observed tracks were counted, regardless of their  C2891001   19 
           orientation. When the voltage was increased from 0.5   C2891001   20 
           MeV to 0.9 MeV the average number of tracks per        C2891001   21 
           expansion increased from 2.7 to 42 with the Be target, C2891001   22 
           and from 7.1 to 13.4 with the H3PO4 target. These      C2891001   23 
           data have been reduced to an absolute yield.           C2891001   24 
ERR-ANALYS (DATA-ERR,500.,1000.) The relative yields are much     C2891001   25 
           more accurate than the absolute ones; the latter may   C2891001   26 
           be in error by as much as a factor of 5 or possibly 10.C2891001   27
