C289100100010 INSTITUTE (1USACAL) C289100100011 FACILITY (ACCEL,1USACAL) C289100100012 DETECTOR (IOCH) The methane-filled cloud chamber. C289100100013 METHOD (REC) The energy distribution of the neutrons was C289100100014 obtained by observing a large number of recoil C289100100015 protons in a cloud chamber. From the stopping power C289100100016 of the gas in the chamber and the range-velocity C289100100017 curve, the energy of the recoil protons was computed. C289100100018 ANALYSIS All observed tracks were counted, regardless of their C289100100019 orientation. When the voltage was increased from 0.5 C289100100020 MeV to 0.9 MeV the average number of tracks per C289100100021 expansion increased from 2.7 to 42 with the Be target, C289100100022 and from 7.1 to 13.4 with the H3PO4 target. These C289100100023 data have been reduced to an absolute yield. C289100100024 ERR-ANALYS (DATA-ERR,500.,1000.) The relative yields are much C289100100025 more accurate than the absolute ones; the latter may C289100100026 be in error by as much as a factor of 5 or possibly 10.C289100100027 HISTORY (20230128C) BP C289100100028 ENDBIB 26 0 C289100100029 NOCOMMON 0 0 C289100100030 ENDSUBENT 29 0 C289100199999 SUBENT C2891002 20230128 20240316 C289100200001 BIB 3 3 C289100200002 REACTION (4-BE-9(D,N)5-B-10,,PY,,TT) C289100200003 SAMPLE Be target.
