Abstract

We formulate the energy-time correlation of neutrons slowing down through multiple elastic scatterings in a homogeneous infinite medium. From the correlation result, we obtain the neutron thermalisation time, expressed through special functions appearing in the calculation steps. We validate our theoretical approach by comparing the ensuing formulae with results of Monte Carlo calculations.
