Neutrons produced 2220600100010 at 0 degrees were selected by a 1.6 m long conical 2220600100011 iron collimator of 11 - 20 mm entrance - exit diame- 2220600100012 ter. In addition, there were two halo collimators, 20 2220600100013 cm long and 25 and 28 mm in diameter. The neutron in- 2220600100014 tensity at 2.6 m from target was about 6.E+6 per sec. 2220600100015 METHOD (TOF) The energies of the neutrons were determined 2220600100016 with time-of-flight. 2220600100017 (COINC) A scintillator telescope was used to detect 2220600100018 the protons. 2220600100019 DETECTOR (SCIN) A thin 0.1 mm scintillator of 3 cm diameter up- 2220600100020 stream to the sample vetoed on charged particles in 2220600100021 the neutron beam. 27 cm beyond the target a 12 cm dia-2220600100022 meter by 0.2 mm thick scintillator, with a 34 mm dia- 2220600100023 meter hole to provide passage for the neutron beam, 2220600100024 fired on charged particles. 1.25 m from the hydrogen 2220600100025 target a 40 x 40 cm2 scintillator of 1 cm thickness 2220600100026 acted as a proton energy detector. Protons of energy 2220600100027 larger than 33 MeV were vetoed by another 40 x 40 cm2 2220600100028 scintillator of 0.5 cm thickness, placed immediately 2220600100029 after the E detector. The neutron detector was a 2220600100030 40 x 40 cm2 piece of scintillator of 5 cm thickness. 2220600100031 A 56 mm hole was cut in each detector for the passage 2220600100032 of the neutron beam. 2220600100033 MONITOR (1-H-1(N,G)1-H-2,,SIG) 2220600100034 The np capture absolute cross section (14.2+-0.2 mu-b)2220600100035 was taken from current measurements in this Lab 2220600100036 COMMENT From compiler: Later data are published at 2220600100037 J,FBS,8,1,1990; but not at the same energy. 2220600100038 See 22229: 76.2 +- 2.1 MeV => 14.130 +- 0.19 mu-b 2220600100039 SAMPLE .A liquid hydrogen target with a volume of 35 mm dia- 2220600100040 meter and 5 mm thickness was placed 2.6 m from the 2220600100041 neutron source. The target volume was limited by 6 2220600100042 micrometer thick aluminized mylar windows. 2220600100043 CORRECTION .Corrections were applied for neutron reactions in the 2220600100044 proton detectors and for the finite efficiency of the 2220600100045 neutron detector. 2220600100046 PART-DET (N,P) 2220600100047 ANALYSIS .The acceptance of the detector system and the effici- 2220600100048 ency of the neutron detector were calculated with 2220600100049 Monte Carlo codes. 2220600100050 ADD-RES .Also differential data, with respect to the azimuthal 2220600100051 angle between the neutron and the proton were taken, 2220600100052 and is presented in a figure. 2220600100053 HISTORY (19921213C) N.O. 2220600100054 (19930329E) 2220600100055 (20121209A) SD: Updated to new date formats,lower case.2220600100056 Corrected according last EXFOR rules and Dict. 2220600100057 SF3, SF4 were corrected in Subents 003, 004. 2220600100058 ENDBIB 56 0 2220600100059 COMMON 2 3 2220600100060 MONIT MONIT-ERR 2220600100061 MICRO-B MICRO-B 2220600100062 1.4200E+01 2.0000E-01 2220600100063 ENDCOMMON 3 0 2220600100064 ENDSUBENT 63 0 2220600199999 SUBENT 22206002 20121209 22342220600200001 BIB 3 5 2220600200002 REACTION (1-H-1(N,G+N)1-H-1,,DE,N) 2220600200003 Bremsstrahlung cross sections from the integral set-up,2220600200004 versus the neutron kinetic energy (in 2 MeV bins) 2220600200005 ERR-ANALYS (DATA-ERR) No information about uncertainties 2220600200006 STATUS (TABLE) .Data from Tbl.1 of Nucl.Phys.
