The gas pressure was adjusted to 4 atm to 1447200100026 provide the desired neutron energy spread in the 1447200100027 energy range investigated. Typically the neutron 1447200100028 energy spread was +-150 keV at 0 deg. 1447200100029 (D-T) The 3H(d,n)4He reaction (Q = 17.59 MeV) was 1447200100030 employed for En=14.8 MeV,replacing the deuterium gas 1447200100031 cell by a tritiated target assembly. It consisted of 1447200100032 a 2-mg/cm2-thick titanium layer loaded with 2.5 Ci of 1447200100033 tritium and evaporated onto a 0.4-mm-thick copper disk 1447200100034 HISTORY (20170601C) Compiled by S.H. 1447200100035 ENDBIB 33 0 1447200100036 NOCOMMON 0 0 1447200100037 ENDSUBENT 36 0 1447200199999 SUBENT 14472002 20170601 14331447200200001 BIB 4 19 1447200200002 REACTION (32-GE-76(N,2N)32-GE-75-M,,SIG) 1447200200003 STATUS (TABLE) Data taken from tab. 1 of the reference 1447200200004 DECAY-DATA (32-GE-75-M,47.7SEC,DG,139.7,1.) 1447200200005 ERR-ANALYS (ERR-1,0.1,2.48,U) Sample photopeak area 1447200200006 (ERR-2,0.36,6.32,U) Monitor photopeak area 1447200200007 (ERR-3,1.05,3.06) Reference cross section 1447200200008 (ERR-4,2.30,5.92) Sample detector efficiency 1447200200009 (ERR-5,0.62,5.30) Monitor detector efficiency 1447200200010 (ERR-6,,0.2) Source geometry and g-ray selfabsorption 1447200200011 (ERR-7,,1.1) Sample half-life 1447200200012 (ERR-8,,0.01) Monitor half-life 1447200200013 (ERR-9,,1.)
