MF= 1 General information
MT=451 Descriptive data and directory
MF= 2 Resonance parameters
MT=151 Resolved and unresolved resonance parameters
No resolved resonance parameters are given.
The 1/v-shped capture cross section is assumed below 12 eV.
At 0.0253 eV, the cross section was normalized to the value
of 0.39 b.
Constant elastic scattering cross sections of 5.31 b were
given below 12 eV.
Unresolved resonance region: 12 eV - 120 keV
The parameters were obtained by fitting to the total and
capture cross sections calculated from POD /1/. The
unresolved parameters should be used only for self-shielding
calculation.

***************************************************************
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 calculated by separate spherical or
coupled-channel optical model code.
