Revision as of 18:58, 22 July 2021
Serpent uses standard ENDF reaction MTs to identify neutron and photon reactions. The numbers are used with detector response functions, microscopic cross section calculations and printed in various output files. Detector responses also include macroscopic cross sections (and similar), identified by negative reaction numbers.
Below are descriptive lists of ENDF reaction MTs and macroscopic reaction numbers. For more information on the MT numbers, see the ENDF Format Manual.^{[1]} It should be noted that even though the notation is very similar to that used by MCNP, there are some differences in the definitions of some response functions.
