keyword=Tripple coinc. neutronsThe plots below are the same as the plot of the halog entry 142133 . Only difference is that the recent plots have one day more data. The second plot below is just the rebinned version of the first plot. We can still see two probable (if not fake) peaks around 300 and 400 channels.
