84-07 DATA OF MF=4 (MT=16,91) AND MF=5 (MT=16,91) WERE REVISED.
COMMENT WAS ALSO MODIFIED.
85-03 MODIFIED BY S. CHIBA
DATA OF MF=3 (MT=59,63) AND MF=4 (MT=59,63) WERE ADDED.
DATA OF MF=3 (MT=16), MF=4 (MT=2,16,53), MF=5 (MT=16)
WERE REVISED.
PSEUDO-LEVEL REPRESENTATION WAS ADOPTED FOR THE
(N,N')ALPHA-D CONTINUUM (MT=51,52,54-56,58,60-62,64-86).
93-12 MODIFIED BY S. CHIBA FOR JENDL-3.2
DATA OF MF=3 (MT=2,3,4,54-56,58,82) AND MF=4 (MT=16,51,52,
54-58,60-86) WERE ADJUSTED MAMUALLY TO REPRODUCE THE DDX
DATA AT 14 AND 18 MEV /1,2,3/.

MT=2 SIG-EL
BELOW 1 MEV, BASED ON THE R-MATRIX CALCULATION.
ABOVE 1 MEV, THE CROSS SECTION WAS OBTAINED BY SUBTRACTING
THE REACTION CROSS SECTION FROM THE TOTAL CROSS SECTION.

ROTATIONAL MODEL WAS ASSUMED. THE COUPLING SCHEME WAS
1+(G.S.) - 3+(2.185) - 2+(4.31) - 1+(5.7).
THE POTENTIAL PARAMETERS WERE;

REPRESENTED BY PSEUDO-LEVELS, BINNED IN 0.5 MEV INTERVALS.
THE (N,N')ALPHA-D CROSS SECTION WAS BASED ON THE MEASURE-
MENT OF ROSEN AND STEWART /15/. THE CONTRIBUTION FROM
MT=53, 59 AND 63 WAS SUBTRACTED SO THAT SIG-T MIGHT BE
EQUAL TO THE SUM OF PARTIAL CROSS SECTIONS. THE CROSS
SECTION FOR EACH LEVEL WAS CALCULATED BY THE 3-BODY PHASE-
SPACE DISTRIBUTION WITH A CORRECTION OF THE COULOMB
INTERACTION IN THE FINAL STATE, ASSUMING ISOTROPIC CENTER-
