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.
Let's see what happens if we increase the energy cuts
Summary table of yields and asymmetry versus energy cuts
Because cnts0 becomes really small quantity we need to analyze errors
To do more investigation we need more statistics. But that is problematically at present moment due to the lack of hard disk space:
- 10M events is about 1G files
- 1000M events is about 100G files
