Abstract
Neutronic formalisms that discretize the neutron slowing down equations in large numerical intervals currently account for the bulk effect of resonances in a given interval by the narrow resonance approximation (NRA). However, there are resonances to which the NRA is not applicable. To stay away from the NRA, the continuous slowing down (CSD) theory of Stacey is invoked. The theory is based on a linear expansion in lethargy of the collision density in integrals of the slowing down equations and has notable success in various problems. The resulting formalism is more accurate than the narrow-resonance formalisms and is equally as efficient.
