Serpent uses standard ENDF reaction MT's to identify neutron and photon reactions. The number are used with detector response functions and printed in various output files. Detector responses also include macroscopic cross sections, identified by negative reaction numbers.
Below are descriptive lists of ENDF reaction MT's and macroscopic reaction numbers. For more information on the MT numbers, see the ENDF Format Manual.[1]
