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.

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. 2.
