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.

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. 2.
