History
09-02 Model calculation was performed using the POD code.
09-11 Data were compiled by K. Shibata, JAEA.
MF= 1 General information
MT=451 Descriptive data and directory
MF= 2 Resonance parameters
MT=151
Resolved resonance parameters were obtained from the data of
Harvey et al. /1/ up to 10 keV. The (n,p) and (n,a) cross
sections were also calculated using their parameters although
Gamma_g and Gamma_a at 203 eV were changed to 2.9 eV and
0.48 eV, respectively.
Unresolved resonance parameters were calculated using the
ASREP code /2/ from 10 keV to 300 keV. The unresolved
parameters should be used only for self-shielding calculation.

MF= 3 Neutron cross sections
MT= 1 Total cross section
Calculated with POD code /3/ above 10 keV. Below 10 keV,
the cross section was given by the sum of the elastic and

10 keV. Below 10 keV, the cross sections are reconstructed
from the resolved resonance parameters given in MF2.

***************************************************************
1. Theoretical models
The POD code is based on the spherical optical model, the
distorted-wave Born approximaiton (DWBA), one-component exciton
preequilibrium model, and the Hauser-Feshbach-Moldauer statis-
tical model. With the preequilibrim model, semi-empirical
pickup and knockout process can be taken into account for
composite-particle emission. The gamma-ray emission from the
compound nucleus can be calculated within the framework of the
exciton model. The code is capable of reading in particle
transmission coefficients calcualted by separate spherical or
coupled-channel optical model code.
