8.3 Energy Group Structure The energy group structure of the Public Libraries consists of 107 groups: 74 groups for fast and 48 for thermal groups, with 12 overlapping groups. They are shown in Table 8.3-1 and Table 8.3-2, respectively. The user can select a thermal-cut-off energy within the overlapping groups, by taking into account of continuity of cross-sections (cf. Sect.1.3), thermal up-scattering and resonance levels in thermal energy range. The cross-sections of the 107 group structure can be collapsed into the cross-sections of user’s fine energy group structure by an asymptotic spectrum (cf. Sect.1.5).
