Plot shows deposited energy (very rough calibration) vs Neutron energy (also very rough calibration). We expect the biggest resonances in the 40K(n,alpha) reaction at ~1 keV and 5 keV. There is an accumulation of counts at those neutron energies and around the expected Alpha energy (~3.5 MeV and ~1.8 MeV). 

In the proposal we expected in total ~2000 counts for those resonances for 4.5E18 protons. The plot shows 1/200 of the total statistics, so what we see is consistent with out estimation.
