Experimental data
2n opening angle obtained after the processing of all the runs with thick uranium target is shown below:
The bin width (x-error) is 7.2 degrees, the total number of bins is 25. Statistical error (y-error) is presented for each bin.
At this stage there is no efficiency normalization involved in the calculation. The main goal is to show that we've got 258 neutrons in all the runs.
Simulation
Two neutrons were sampled isotropically and opening angle was observed for two cases when (1) two neutrons hit the same detector (N(same)) and (2) two neutrons hit two different detectors (N(different)). After that the plot of N(different)/(N(same)+N(different)) was made.
The total number of neutron pairs sampled was
