mf=1 General information
mt=451 Descriptive data and dictionary
mf=2 Resonance parameters
mt=151 Resolved resonance parameters
Resolved parameters for MLBW formula were given in the energy
region from 1.0e-5 eV to 100 keV. Parameters were taken from
ref./5/, for positive resonances. Parameters for negative
resonance were obtained so that the reproduced cross sections
for both scattering and capture gave the 2200 m/s values of
3.1+-0.2 and 1.7+-0.2 barns, respectively/5/. The scattering
radius was assumed to be 4.5 fermi instead of 3.6 fermi in
ref./5/. Calculated 2200 m/sec cross sections and resonance
integrals are as follows:
2200 m/s cross section(b) res. integral(b)
elastic 3.10
capture 1.70 1.43
total 4.80
mf=3 Neutron cross sections
Below 100 kev, no background cross section was given.
The calculation with sincros-ii system/2/ was made by adopting
Walter-Guss omp modified by Yamamuro/2/ for neutron, Perey omp
/6/ for proton, Lemos omp modified by Arthur and Young/7/
for alpha, Lohr-Haeberli omp/8/ for deuteron, Becchettii-
Greenlees omp/9/ for triton and he-3, and standard level
density parameters of sincros-ii system.
mt=1 Total
Below 100 keV, created from the resonance paranmeters.
Above 100 keV, optical and statistical model calculation was
made with the casthy code/10/.
The optical potential parameters used are:
V = 50.75 - 0.120*En, Vso = 4.72 (MeV)
Ws = 10.9 - 0.234*En, Wv = 0.0 (MeV)
r = 1.26, rs = 1.02, rso = 1.16 (fm)
a = 0.52, aso = 0.52, b = 0.40 (fm)
mt=2 Elastic scattering
Obtained by subtracting the sum of the partial cross sections
from the total cross section.
mt=4, 51-66, 91 Inelastic scattering
The cross sections were taken from JENDL fusion file. the
level scheme was based on ref./4/ Contributions of the
direct process were calculated for the levels marked with '*'.

mt=16, 22 (n,2n), (n,na)
Adopted from JENDL fusion file. Theoretical calculation was
made with sincros-ii. The (n,2n) results were normalized to
0.200 b at 14.9 MeV systematics by Kasugai/11/
mt=28 (n,np)
Obtained from from the sincros-ii calculation made with the
the egnash code/2/.
mt=102 Capture
Calculated with the casthy code/10/ and normalized to 65.5 mb
at 30 keV. Added the semidirect component calculated with
the quick gnash code/16,17/.
mt=103 (n,p)
Taken from JENDL dosimetry file/14/.
mt=107 (n,a)
Calculated with the gnash code/12/.
mf=4 Angular distributions of secondary neutrons
mt=2
Calculated with the casthy code/10/,newly for JENDL-3.3.
mt=51-66
Taken from JENDL fusion file/1/.
mf=6 Energy-angle distributions of secondary particles
Taken from JENDL fusion file/1/.
- Energy distributions of secondary neutrons were replaced
by those calculated by egnash2. The ddx's of the
continuum neutrons were calculated by Kumabe's systema-
tics /3/ using f15tob /1/. The precompound/compound
ratio was calculated by the sincros-ii code system/2/.
mt=16, 22, 28, 91
Based on modified Kumabe's systematics/1/.
mt=203, 207
Based on kalbach's 1988 systematics/13/.

mt=51-66 were given as the transition probability arrays.
mt=16, 22, 28, 91, 102, 103, 104, 107 were calculated with
the egnash code/2/ and processed by the gamfil2 code/15/.
mt=102 was calculated with the casthy code/10/.
