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 180 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
0.7+-0.3 and 2.2+-0.3 barns, respectively/5/. The scattering
radius was assumed to be 4.5 fermi instead of 4.0 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 0.69
capture 1.83 0.89
total 2.52
mf=3 Neutron cross sections
Below 180 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 180 keV, created from the resonance parameters
Above 180 keV, optical and statistical model calculation was
made with casthy code/2/.
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, 51-65, 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, 28, 103 (n,2n), (n,np), (n,p)
Adopted from JENDL fusion file. Theoretical calculation was
made with sincros-ii/2/. The results were normalized to
(n,np)+(n,d) 0.00897b at 14.98 MeV measured by Ikeda et al.
/10/ , (n,p) 0.023 b at 14.7 MeV measured by Qaim et al./11/
mt=22 (n,na)
Obtained from from the sincros-ii calculation made with the
the egnash code/2/.
mt=102 Capture
Below 180 keV, created from the resonance parameters
Above 180 keV, calculated with the casthy code/12/ and
normalized to 22.5 mb at 30 keV, and added the semidirect
component calculated with the quick gnash code/15,16/.
mt=107 (n,a)
Obtained from from the sincros-ii calculation made with the
the egnash code/2/.
mf=4 Angular distributions of secondary neutrons
mt=2
Calculated with the casthy code/10/,newly for JENDL-3.3.
mt=51-65
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/.
