Follow are some Monte Carlo simulations of 2n correlations. One neutron are from one FF, two neutrons per fission. No accidental neutron was considered, all neutrons are correlated. Total 10M events was simulated. Every neutron was sampled up to 10 MeV. The polarization of gammas are zero.


2n Asymmetry versus Energy Cut

It was been shown by Dr Dale that Asymmetry of 2n correlations (anti-parallel/parallel) is the strong function of energy cuts and increases as energy cut increases.

Need to analyze statistical error because cnts0 becomes really small quantity
