ENTOSAN. A Program for the Calculation of Fine Group Cross Section Values from ENDF/B Data

摘要

The program ENTOSAN calculates group cross section values for a fine group structure from data in the ENDF/B format. The main feature of the program is the direct calculation of the group cross section contribution of the various parts of the ENDF/B data (i.e. resonance parameters and smooth data) without the calculation of point data in a fixed energy pattern for the complete energy range of interest. Noteworthy is that in this approach the resonance contributions are treated in a sequential way. The output group structure incorporated in the program is a SAND-II 640 groups structure, covering the energy range from 10 exp -10 to 20 MeV. (Atomindex citation 12:627970)
