JENDL FUSION FILE /1/ (AS OF DEC. 1993)
EVALUATED BY K.KOSAKO (NEDAC) AND S. CHIBA (NDC/JAERI)
COMPILED BY K.KOSAKO.
- THE INELASTIC SCATTERING CROSS SECTIONS AND ANGULAR
DISTRIBUTIONS OF INELASTICALLY SCATTERED NEUTRONS (EXCEPT
CONTINUUM INELASTIC) WERE CALCULATED WITH CASTHY2Y AND
DWUCKY IN SINCROS-II SYSTEM/2/ INCLUDING CONTRIBUTIONS
FROM DIRECT REACTIONS.
- THE (N,2N), (N,NA), (N,NP) AND (N,P) REACTION CROSS
SECTIONS (MT=16, 22, 28, 103) WERE CALCULATED BY EGNASH2
IN THE SINCROS-II.
- ENERGY DISTRIBUTIONS OF SECONDARY NEUTRONS WERE REPLACED
BY THOSE CALCULATED BY EGNASH2. THE DDX'S OF THE
CONTINUUM NEUTRONS WERE CALCULATED BY KUMABE'S SYSTEMA-
TICS /3/ USING F15TOB /1/. THE PRECOMPOUND/COMPOUND
RATIO WAS CALCULATED BY THE SINCROS-II CODE SYSTEM.
- THE RESONANCE PARAMETERS, TOTAL, CAPTURE AND (N,A) CROSS
SECTIONS AND ANG. DISTRIBUTIONS OF ELASTICALLY SCATTERED
NEUTRONS WERE TAKEN FROM JENDL-3.1.
- OPTICAL-MODEL, LEVEL DENSITY AND OTHER PARAMETERS USED IN
THE SINCROS-II CALCULATION ARE DESCRIBED IN REF./2/.
LEVEL SCHEMES WERE DETERMINED ON THE BASIS OF ENSDF/4/.
-------------------------------------------------------------
MF=1 GENERAL INFORMATION
MT=451 DESCRIPTIVE DATA AND DICTIONARY
MF=2 RESONANCE PARAMETERS
MT=151 RESOLVED RESONANCE PARAMETERS
RESOLVED PARAMETERS FOR MLBW FORMULA WERE GIVEN IN THE ENERGY
REGION FROM 1.0E-5 EV TO 100 KEV. PARAMETERS WERE TAKEN FROM
REF./5/, FOR POSITIVE RESONANCES. PARAMETERS FOR NEGATIVE
RESONANCE WERE OBTAINED SO THAT THE REPRODUCED CROSS SECTIONS
FOR BOTH SCATTERING AND CAPTURE GAVE THE 2200 M/S VALUES OF
3.1+-0.2 AND 1.7+-0.2 BARNS, RESPECTIVELY/5/. THE SCATTERING
RADIUS WAS ASSUMED TO BE 4.5 FERMI INSTEAD OF 3.6 FERMI IN
REF./5/. CALCULATED 2200 M/SEC CROSS SECTIONS AND RESONANCE
INTEGRALS ARE AS FOLLOWS:
2200 M/S CROSS SECTION(B) RES. INTEGRAL(B)
ELASTIC 3.10
CAPTURE 1.70 1.44
TOTAL 4.80
MF=3 NEUTRON CROSS SECTIONS
BELOW 100 KEV, NO BACKGROUND CROSS SECTION WAS GIVEN.
FOR JENDL-3.2, ALL CROSS-SECTION DATA EXCEPT FOR THE TOTAL,
CAPTURE AND (N,A) WERE ADOPTED FROM JENDL FUSION FILE. THE
CALCULATION WAS MADE WITH SINCROS-II SYSTEM/2/ BY ADOPTING
WALTER-GUSS OMP MODIFIED BY YAMAMURO/2/ FOR NEUTRON, PEREY OMP
/6/ FOR PROTON, LEMOS OMP MODIFIED BY ARTHUR AND YOUNG/7/ FOR
ALPHA, LOHR-HAEBERLI OMP/8/ FOR DEUTERON, BECCHETTII-GREENLEES
OMP/9/ FOR TRITON AND HE-3, AND STANDARD LEVEL DENSITY
PARAMETERS OF SINCROS-II SYSTEM.
MT=1 TOTAL
OPTICAL AND STATISTICAL MODEL CALCULATION WAS MADE WITH
CASTHY CODE/10/. THE OPTICAL POTENTIAL PARAMETERS USED ARE:
V = 50.75 - 0.120*EN, VSO = 4.72 (MEV)
WS = 10.9 - 0.234*EN, WV = 0.0 (MEV)
R = 1.26, RS = 1.02, RSO = 1.16 (FM)
A = 0.52, ASO = 0.52, B = 0.40 (FM)
MT=2 ELASTIC SCATTERING
OBTAINED BY SUBTRACTING THE SUM OF THE PARTIAL CROSS SECTIONS
FROM THE TOTAL CROSS SECTION.
MT=4, 51-66, 91 INELASTIC SCATTERING
THE CROSS SECTIONS WERE TAKEN FROM JENDL FUSION FILE. THE
LEVEL SCHEME WAS BASED ON REF./4/ CONTRIBUTIONS OF THE
DIRECT PROCESS WERE CALCULATED FOR THE LEVELS MARKED WITH '*'.

MT=16, 22, 28, 103 (N,2N), (N,NA),(N,NP), (N,P)
ADOPTED FROM JENDL FUSION FILE. THEORETICAL CALCULATION WAS
MADE WITH SINCROS-II. THE RESULTS WERE NORMALIZED TO
(N,2N) 0.200 B AT 14.9 MEV SYSTEMATICS BY KASUGAI/11/
(N,NP)+(N,D) 0.080 B AT 14.98 MEV MEASURED BY IKEDA ET AL./12/
