A generalized theory of the Rossi-α method is shown and is applied to the analysis of an experiment made with a remotely subcritical system.
Starting from the neutron transport equation, a general expression for the probability of detecting correlated neutrons is given, which is a function of the positions and sensitivities of the neutron detectors used in the experiment.
Some numerical examples for this expression are also given under the one-group diffusion approximation for comparison with the experiment. The agreement between them is satisfactory.
