Abstract
A stochastic theory for a branching process in a neutron population with two energy levels is used to assess the applicability of the di?erential self-interrogation Feynman-alpha method by numerically estimated reaction intensities from Monte Carlo simulations. More specifically, the variance to mean or Feynman-alpha formula is applied to investigate the appearing exponentials using the numerically obtained reaction intensitie
