Shibata (JAEA) /1/ using the POD code. 13-04 The comment data were corrected. 18-05 Activation cross sections added by K.Shibata. 21-11 revised by O.Iwamoto (MF8/MT4) added 21-11 above 20 MeV, JENDL/ImPACT-2018 merged by O.Iwamoto 21-11 (MF6/MT5) recoil spectrum added by O.Iwamoto MF= 1 General information MT=451 Descriptive data and directory MF= 2 Resonance parameters MT=151 Resolved and unresolved resonance parameters Resolved Resonance Parameters (MLBW; below 50 eV) The resonance parameters of 8 levels up to 330 eV were obtained by Anufriev et al./2/ Their parameters were adopted. In addition, a negative resonance was assumed at -3.0 eV and its parameters were determined so that the capture cross section at 0.0253 eV was about 10 b. An upper bounday of the resolved resonance region was set at 50 eV, because level missing was obvious above this energy. Unresolved resonance region: 50 eV - 100 keV The parameters were obtained by fitting to the calculated total and capture cross sections. The unresolved resonance parameters obtained should be used only for self-shielding calculation. URP's were re-calculated by fitting to the total and capture cross sections calculated by POD /3/.

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.
