Because of the bulging 22951 1 16 of the foils, their thickness was almost 30% smallest 22951 1 17 at the center and the effective target length was 22951 1 18 14.2-mm. 22951 1 19 INC-SOURCE (D-D) The neutron beam was produced via 22951 1 20 the H-2(d,N)He-3 reaction with 15-MeV deuterons 22951 1 21 incident on a 42-mm long gas target, which was closed 22951 1 22 with 10 mu-meter thick Havar foils. 22951 1 23 INC-SPECT At a typical deuteron beam intensity of 500-Na, the 22951 1 24 high-energy neutron flux in the monoenergetic peak 22951 1 25 from the d(d,n)He-3 reaction was 2.9E+6/S/cm**2 at the22951 1 26 scattering target with an average energy En=17.36 MeV 22951 1 27 and an energy spread of 170 keV(FWHM) 22951 1 28 DETECTOR (TELES,SIBAR,SIBAR) A counter telescope consisting 22951 1 29 of three 150 mm2 Si-surface barrier detectors, 22951 1 30 two delta-E detectors of 220 and 506 mu-meter thick, 22951 1 31 respectively, and 1500 micro-meter thick E-detector. 22951 1 32 The last detector was calibrated from the back with 22951 1 33 alpha-particles from Am-241 source for monitoring 22951 1 34 of its performance during the measurements. 22951 1 35 (COIN,SIBAR,SIBAR) The three detectors were operated 22951 1 36 in a conventional fast-slow coincidence. 22951 1 37 ADD-RES (COMP) MONTE-CARLO simulations based on rigorous three 22951 1 38 body calculations using Cd-bonn and two other high- 22951 1 39 quality potentials for the nucleon-nucleon 22951 1 40 interaction. 22951 1 41 HISTORY (20070131C) SM/MM 22951 1 42 (20070309A) Last corrections have been done - SM. 22951 1 43 (20220102A) SD: Correction in Subent 002. 22951 1 44 ENDBIB 42 0 22951 1 45 COMMON 2 3 22951 1 46 EN EN-RSL-FW 22951 1 47 MEV KEV 22951 1 48 17.36 170. 22951 1 49 ENDCOMMON 3 0 22951 1 50 ENDSUBENT 49 0 22951 199999 SUBENT 22951002 20220102 230722951 2 1 BIB 5 7 22951 2 2 REACTION (1-H-2(N,2N)1-H-1,,DE,P,RAW) Number of counts per 22951 2 3 channel 22951 2 4 FLAG (1.)
