COMPILATION
EVALUATED DATA WERE COMPILED BY T.FUKAHORI (JAERI).
90-10 MF=5: SPECTRA WERE MODIFIED AT LOW ENERGIES OF EMITTED
NEUTRONS BY T.ASAMI(DATA ENGINEERING CO. LTD.)
90-11 REEVALUATION WAS MADE FOR THE DATA CONCERNING WITH THE
NEUTRON EMISSION DOUBLE DIFFERENTIAL CROSS SECTIONS.
THE INELASTIC SCATTERING CROSS SECTIONS AND THE ANGULAR
DISTRIBUTIONS FOR THE INELASTICALLY EMITTED NEUTRONS WERE
REVISED CONSIDERABLY/25/.

MT=51-90 SIG-IN
THE CROSS SECTIONS WERE CALCULATED WITH THE STATISTICAL
MODEL. THE LOW-ENERGY PORTION WAS ANALYZED WITH THE
RESONANCE THEORY/10/. FOR MT=51 TO 73, THE DIRECT
COMPONENTS WERE CALCULATED WITH THE DWUCK CODE/26/. FOR
74 TO 90, PSEUD-LEVELS WERE ASSUMED AND ADJUSTED TO FIT
TO THE EXPERIMENTAL DATA/27/.
THE OPTICAL POTENTIAL PARAMETERS USED ARE THE FOLLOWING
/11/:
V = 50.08-0.01E , WS = 9.0 + 0.62E, VSO = 5.5 (MEV)
R = 1.22 , RS = 1.45 , RSO = 1.15 (FM)
A = 0.66 , B = 0.13 , ASO = 0.50 (FM).
