The following pre-defined energy group structures are available to be used with the ene card. The group boundaries are listed in in the order of increasing lethargy.

All energy group structures listed here have also extended versions where the names have a suffix of _ext, for example nj19_ext. These energy group structures have upper and lower bounds of infinity and zero, respectively. When using these energy group structures, for example the group constants are tallied with all energies also used during the Serpent simulations.
