In order to verify the Feynman-alpha formula with stationary multiple emission sources [Pázsit, I., Yamane, Y., 1998. Nuclear Instruments and Methods A403, 431–441], a series of experiments were performed by using three different neutron sources, i.e., an Am–Be, a 252 Cf, and a randomly triggered D–T pulsed neutron generator. As a result, it was found that the prompt neutron decay constant...
The Rossi-alpha formula for subcritical systems driven by a pulsed neutron source was derived with a solution technique that can effectively take different shape functions of the pulsed neutron source into account. The result of derivation showed that the present formula consists of the correlated and uncorrelated terms and an oscillating term whose period was identical to that of the pulsed neutron...
