(3,2), (3,4), (3,58) AROUND 3 MEV.

-------------------------------------------------------------
JENDL FUSION FILE /1/ (AS OF SEP. 1993)
EVALUATED AND COMPILED BY S. CHIBA (NDC/JAERI)
DATA WERE TAKEN FROM JENDL-3.1 EXCEPT FOR THE FOLLOWING:
THE NEUTRON ENERGY DISTRIBUTIONS OF MT=16, 17, 22, 28
AND 91 WERE REPLACED WITH CALCULATED VALUES WITH SNICROS-
II/2/. HOWEVER, THOSE OF MT=16 AND 91 ABOVE 17 MEV WERE
TAKEN FROM JEND L-3.1 BECAUSE THEY REPRODUCED THE DATA
MEASURED BY MATSUYAMA ET AL./3/ AT 18 MEV BETTER THAN THE
SINCROS-II CALCULATION. THE ANGULAR DISTRIBUTIONS OF
CONTINUUM NEUTRONS WERE CREATED BY F15TOB/1/. THE MSD/MSC
RATIO WAS TAKEN FROM THE SINCROS-II CALCULATION, AND
KUMABE'S SYSTEMATICS/4/ WAS USED.
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/5/.

MT=4,51-62,91 INELASTIC SCATTERING
STATISTICAL MODEL CALCULATIONS WERE MADE WITH THE SINCROS
SYSTEM /2/ USING THE MODIFIED WALTER-GUSS POTENTIAL
PARAMETERS FOR NEUTRONS. FOR MT=51,52,58,62, THE EXPERI-
MENTAL DATA OF SMITH ET AL./10/ WERE ADOPTED BELOW 5 MEV.
THE CALCULATED CROSS SECTION OF MT=91 WAS MODIFIED SO AS
TO REPRODUCE THE MEASUREMENTS OF THE TOTAL INELASTIC CROSS
SECTION BELOW 8 MEV. THE DIRECT-PROCESS COMPONENTS WERE
CONSIDERED FOR THE LEVELS OF MT=51,52,58,91 BY THE DWBA
CALCULATIONS.
THE LEVEL SCHEME IS GIVEN AS FOLLOWS:
NO. ENERGY(MEV) SPIN-PARITY
G.S. 0.0 9/2 -
1. 0.8964 7/2 -
2. 1.6085 13/2 +
3. 2.4300 1/2 +

11. 2.7660 5/2 +
12. 2.8220 5/2 -
LEVELS ABOVE 2.85 MEV WERE ASSUMED TO BE OVERLAPPING.
MT=16,17,22,28,103,104,107 (N,2N),(N,3N),(N,N'A),(N,N'P),(N,P)
(N,D) AND (N,A) CROSS SECTIONS
CALCULATED WITH SINCROS/2/. OPTICAL POTENTIAL PARAMETERS
FOR PROTON, ALPHA-PARTICLE AND DEUTERON WERE TAKEN FROM
THE WORKS OF PEREY/11/, LEMOS/12/ AND LOHR AND HAEVERLI
/13/, RESPECTIVELY. THE CALCULATED (N,P) CROSS SECTION
WAS MULTIPLIED BY 0.3333 IN ORDER TO FIT TO THE
EXPERIMENTAL DATA /14,15,16/ AROUND 14 MEV.

1.0E-5 EV TO 200 KEV: RESONANCE PARAMETERS GIVEN BETWEEN
30 KEV AND 200 KEV.
