THERMAL CROSS SECTIONS
N,GAMMA=3.8 MB+/-20PC CALCULATED BY S.F.MUGHABGHAB
(MU78) USING METHOD OF LANE + LYNN (SEE DOCUMENT)
N,ALPHA=235 MILLIBARNS WEIGHTED AVERAGE OF(HA61),
(SE56),(MA47).
N,ABSORPTION=238.8 MB. TOTAL OF ABOVE.
THESE CROSS SECTIONS ASSUMED TO BE I/V TO APPROX 100KEV.
****************************************************************
SINCE VIRTUALLY NO EXPERIMENTAL DATA AVAILABLE,THIS EVALUATION
IS ALMOST TOTALLY CALCULATED WITH NUCLEAR MODEL CODES.
****************************************************************
MF=2 MT=151 NO RESONANCE PARAMETER DATA AVAILABLE.SMOOTH CROSS
SECTIONS CALCULATED IN THE RESONANCE REGION CONSTRUED AS
"AVERAGE"CROSS SECTIONS.
****************************************************************
MF=3 MT=1 TOTAL CROSS SECTION IS CALCULATED AS SUM OF THE CROSS
SECTIONS LISTED BELOW.IN GOOD AGREEMENT WITH PRELIMINARY
MEASUREMENTS BY AUCHAMPAUGH(AU77).
**** MT=2 TOTAL ELASTIC CROSS AT LOW ENERGY DERIVED FROM
EXP.MEASURED COHERENT SCATTERING AMPLITUDE. (VA68) HIGH
ENERGY CROSS SECTION CALCULATED WITH NUBAK (AN IN-HOUSE
VERSION OF"ABACUS")(AU64)
**** MT=4 DERIVED FROM THE SUMMATION OF MT=51-62 AND MT=91
**** MT=51-62,91 THESE LEVELS CALCULATED WITH NUCLEAR MODEL
CODES "MODNEW"(AN IN-HOUSE VERSION OF UHL'S CODE)(UH72)
MODIFIED FOR GILBERT AND CAMERON PARAMETERS(SEE DOCUMENT
ABOVE) AND"COMNUC" (DU70). COMNUC RESULTS NORMALIZED TO
HIGH ENERGY MODNEW RESULTS TO ALLOW FOR COMPETING REACTIONS
**** MT=16 CALCULATED WITH"MODNEW"(UH72) NO NORMALIZATION
AVAILABLE.
**** MT=22 CALCULATED WITH"MODNEW"(UH72) NO NORMALIZATION
AVAILABLE.
**** MT=28 CALCULATED WITH"MODNEW"(UH72) NO NORMALIZATION
AVAILABLE.
**** MT=102 CALCULATED WITH"COMNUC"(DU70).LEVEL SPACING ASSUMED
AND GAMMA GAMMA ASSUMED.2PI GAMMA GAMMA OVER D =0.000063.
CROSS SECTION AT 14.0 MEV=0.1MILLIBARN.
**** MT=103 CALCULATED WITH"MODNEW"(UH72).NEUTRON YIELD
ACTIVATION MEASUREMENT AT 14.1 MEV=21.5+-1.7 MILLIBARNS BY
MENLOVE (ME70) SUPPORTS CALCULATION VALUE 14.1MEV=40 MILLI-
BARNS.
**** MT=104 CALCULATED WITH"MODNEW(UH72) NO NORMALIZATION
AVAILABLE.
**** MT=107 N,ALPHA CROSS SECTION EXOERGIC.CALCULATED WITH
"MODNEW"(UH72).NO NORMALIZATION AVAILABLE.CALCULATIONS BY
ARTHUR(AR77) WITH LASL VERSION OF"COMNUC" SHOW SIMILAR
SHAPE AND MAGNITUDE.

MF=4 MT=2 ELASTIC ANGULAR DISTRIBUTIONS CALCULATED WITH"NUBAK"
AS A KLASS 3 PROBLEM(AU64)
**** MT=16,22,28,91 GIVEN AS ISOTROPIC IN LAB SYSTEM
**** M=51-62 GIVEN AS ISOTROPIC IN THE C.O.M. SYSTEM
