HISTORY
94-3 NEW EVALUATION CONSTRUCTED FROM ISOTOPE DATA
MF=1 GENERAL INFORMATION
MT=451 COMMENTS AND DICTIONARY
MF=2 RESONANCE PARAMETERS
MT=151 RESOLVED RESONANCE PARAMETERS
RESOLVED RESONANCE PARAMETERS FOR MLBW FORMULA.(BELOW 226.0 KEV)
BELOW 226 KEV BACKGROUND CROSS SECTION WAS ALSO GIVEN.
BETWEEN 202 TO 226 KEV: CL-37 SMOOTH CROSS SECTION WERE ADDED
AS A BACKGROUND CROSS SECTION. BELOW 226KEV CL-35(N,P),(N,A)
CROSS SECTION WAS ADDED ALSO BACKGROUND CROSS SECTION.
THE DATA WERE CONSTRUCTED FROM THE EVALUATED CROSS SECTIONS
FOR CL-35 AND CL-37, CONSIDERING THEIR ABUNDANCES/1/.
CALCULATED 2200-M/S CROSS SECTIONS AND RES. INTEGRALS (BARNS)
2200 M/S RES. INTEG.
TOTAL 49.03 -
ELASTIC 15.89 -
CAPTURE 33.14 13.57
MF=3 NEUTRON CROSS SECTIONS
BELOW 226 KEV, RESONANCE PARAMETERS WERE GIVEN.
ALSO BACKGROUND CROSS SECTIONS WERE GIVEN TO TOTAL,ELASTIC,
CAPTURE,(N,P) AND (N,A) PARTIAL CROSS SECTIONS.
ABOVE 202 KEV, THE TOTAL, ELASTIC AND INELASTIC SCATTERING, AND
CAPTURE CROSS SECTIONS WERE CALCULATED WITH THE OPTICAL AND
STATISTICAL MODEL CODE CASTHY/2/. OPTICAL POTENTIAL PARAMETERS
USED WERE AS FOLLOWS.

---------------------- ------------ ---------------
V = 46.68-0.3459E , R0 = 1.450 , A0 = 0.308
WS = 3.584+1.224E , RS = 1.433 , AS = 0.338
WSO= 6.2 , RSO= 1.200 , ASO= 0.638
THE LEVEL SCHEME WAS ADOPTED FROM ENSDF FILE FOR EACH ISOTOPES.
