In unreflected reactors, the probability of detecting chain-related counts is given by the well known Rossi-{alpha} expression. Using this the author derives an expression for the effective delayed neutron fraction, {beta}. He demonstrates that this expression for {beta} is equally applicable for a reflected systems in which two alphas are experimentally observed
