1-H - 2 JAERI EVAL-JUL82 K.SHIBATA,T.NARITA,S.IGARASI JAERI-M 83-006 DIST-MAY10 20100324 ----JENDL-4.0 MATERIAL 128 -----INCIDENT NEUTRON DATA ------ENDF-6 FORMAT HISTORY 83-01 New evaluation for JENDL-2. Details are given in ref. /1/. Data were compiled by the authors. 83-11 mf=2 was added. 87-05 Carried over from JENDL-2. 93-04 JENDL-3.2 compiled by T.Nakagawa (ndc/jaeri) 96-08 ddx were re-calculated with the faddeev formalism. ***** modified parts for JENDL-ff ******************** (6,16) neutron and proton ddx *********************************************************** 01-07 JENDL-3.3 Taken from JENDL fusion file. Compiled by K.Shibata (jaeri). ***** modified parts for JENDL-3.3 ******************** (1,451) Updated (3,251) Deleted (4,2) Transformation matrix deleted *********************************************************** 03-09 JENDL-4 Angular distribution of elastic scattering was replaced with a Faddeev calculation with PEST (Paris EST expanded) potential by S. Chiba (to be published). Compiled by S. Chiba *********************************************************** 10-03 Gamma-ray production data were added to the dataset. mf=1 General information mt=451 Descriptive data and dictionary mf=2 Resonance parameters mt=151 Scattering radius only mf=3 Neutron cross sections 2200-m/s cross sections and calculated res. integrals. 2200-m/s res. integ. elastic 3.389 b - capture 0.00055 b 0.000286 b total 3.390 b - mt=1 Total Based on a least-squares fit to the experimental data of /2/-/8/. mt=2 Elastic elastic = total - (n,2n) - capture. mt=16 (n,2n) Based on a least-squares fit. Data listed in /9/-/11/ were used. mt=102 Capture Below 1 keV, 1/v form normalized to the data of Ishikawa /12/. Above 1 keV, evaluated on the basis of the inverse reaction /13/. mf=4 Angular distributions of secondary neutrons mt=2 Calculated from the three-body model based on the faddeev equation /14/. 03-09 JENDL-4 Angular distribution of elastic scattering was replaced with a Faddeev calculation with PEST (Paris EST expanted) potential by S. Chiba. mf=6 Energy-angle distributions mt=16 Three-body model calculations Distributions of neutrons and protons given. mf=12 Photon production multiplicities mt=102 A single primary photon is available. mf=14 Photon angular distributions mt=102 Isotropic distribution.
