MoNA was arranged 1437800100022 in 9 vertical layers of 16 horizontal scintillator 1437800100023 bars each. The front face of the first layer was 1437800100024 placed at 8.27 m from the reaction target. For the 1437800100025 present analysis, only the first 6 layer and the 1437800100026 center 1.6m of the 2m length were used. The 1437800100027 horizontal and vertical acceptances were +-2.8deg and 1437800100028 +-3.1deg, respectively. Each bar has a photomultiplier 1437800100029 tube mounted on each end. 1437800100030 (DRFTC) Two additional cathode readout drift chambers 1437800100031 separated by 1m determined the trajectories of 1437800100032 projectile-like fragments 1437800100033 (TELES,SCIN,SCIN) A telescope consisting of a thin 1437800100034 and a thick plastic scintillator was used as 1437800100035 fragment trigger and for particle identification. 1437800100036 Additional thin plastic scintillator positioned 1437800100037 before the target provided the start signal for 1437800100038 time of flight measurement. 1437800100039 METHOD (TOF,EDE) 1437800100040 INC-SOURCE A 120 MeV/nucleon 18-O beam from the Coupled 1437800100041 Cyclotron Facility bombarded a 2850 mg/cm2 9Be 1437800100042 target. The secondary 8Li beam was selected by the 1437800100043 A1900 fragment separator utilizing an 825 mg/cm2 1437800100044 aluminum wedge degrader. The average beam intensity 1437800100045 approx. 150 000/s, the mean energy was 69.5 1437800100046 MeV/nucleon, and the energy dispersion could be best 1437800100047 described by a rounded rectangle with FWHM = 1.8 1437800100048 MeV/nucleon. 1437800100049 HISTORY (20140218C) Compiled by S.H. 1437800100050 ENDBIB 48 0 1437800100051 NOCOMMON 0 0 1437800100052 ENDSUBENT 51 0 1437800199999 SUBENT 14378002 20140218 13981437800200001 BIB 5 14 1437800200002 REACTION (3-LI-7(N,G)3-LI-8,,SIG,,,DERIV) 1437800200003 STATUS (CURVE) Data presented in fig. 9 of the reference 1437800200004 digitized. Waiting for data from author 1437800200005 SAMPLE 56.7 mg/cm2 lead sample 1437800200006 ANALYSIS (DTBAL) Photodesintegration of 8Li was accomplished by 1437800200007 virtual photons in Coulomb scattering of 8Li with 1437800200008 energy of 69.5+-1.9 MeV on lead and carbon target. 1437800200009 The decay energy from breakup of 8Li was calculated 1437800200010 from kinematics. Decay energy spectrum was converted 1437800200011 to the Coulomb dissociation function and subsequently 1437800200012 to the photodisintegration cross section. Detailed 1437800200013 balance was used to convert 8Li photodisintegration 1437800200014 cross section to neutron capture cross section on 7Li 1437800200015 ERR-ANALYS (DATA-ERR) No information given 1437800200016 ENDBIB 14 0 1437800200017 NOCOMMON 0 0 1437800200018 DATA 3 24 1437800200019 EN-CM DATA DATA-ERR 1437800200020 KEV MICRO-B MICRO-B 1437800200021 3.95E+00 2.91E+01 4.26E+00 1437800200022 2.05E+01 1.98E+01 2.67E+00 1437800200023 4.41E+01 1.77E+01 2.17E+00 1437800200024 7.31E+01 1.47E+01 1.92E+00 1437800200025 1.07E+02 1.34E+01 1.76E+00 1437800200026 1.44E+02 1.17E+01 1.53E+00 1437800200027 1.85E+02 1.05E+01 1.37E+00 1437800200028 2.30E+02 9.61E+00 1.22E+00 1437800200029 2.77E+02 8.86E+00 1.16E+00 1437800200030 3.27E+02 8.09E+00 1.09E+00 1437800200031 3.81E+02 7.56E+00 1.02E+00 1437800200032 4.34E+02 7.00E+00 9.70E-01 1437800200033 4.94E+02 6.73E+00 9.58E-01 1437800200034 5.55E+02 6.01E+00 8.32E-01 1437800200035 6.14E+02 6.09E+00 8.67E-01 1437800200036 6.80E+02 5.46E+00 8.20E-01 1437800200037 7.46E+02 5.77E+00 8.88E-01 1437800200038 8.15E+02 5.61E+00 8.43E-01 1437800200039 8.90E+02 5.54E+00 8.31E-01 1437800200040 9.55E+02 4.77E+00 7.53E-01 1437800200041 1.04E+03 4.90E+00 7.73E-01 1437800200042 1.11E+03 5.98E+00 9.21E-01 1437800200043 1.20E+03 5.44E+00 8.58E-01 1437800200044 1.28E+03 5.04E+00 7.75E-01 1437800200045 ENDDATA 26 0 1437800200046 ENDSUBENT 45 0 1437800299999 ENDENTRY 2 0 1437899999999
