| | CROSS-SECTION LIBRARIES |
 | | Using the card-image form of a coupled library with cross sections ordered as shown in Table 10.2, "Arrangement of Data in a Coupled Neutron-Gamma Library Table," on page 10-18 (for no upscatter), the isotopic cross sections for each Legendre order of scatter carry data arranged as shown in Table 10.3. |
 | | In this form neutrons appear to "downscatter" into the gamma-ray groups as a result of gamma production resulting from neutron interactions but gamma- rays do not "upscatter" into neutron groups, i.e., there is no neutron production via photoneutron, or gamma-n, reactions. |
 | | That table shows the contents of a card-image cross-section table for a 7-group coupled set (4 neutron, 3 gamma groups). |
