Christmas Light
’Twas the night before Christmas when all through the house
No electrons were flowing through even my mouse.
All devices were plugged by the chimney with care
With the hope that St. Nikola Tesla would share.

An experimental method of measuring epithermal-neutron spectra by use of resonance activation detectors is presented. Measurements of the change in cadmium ratio with varying dilutions of the same isotope are related to the self-screening properties of selected neutron resonances. The neutron spectra obtained in this way are compared with time-of-flight measurements. A wide range of 235U- or 233U-fueled, BeO-moderated substitution lattices were studied. Marked deviation from the 1/E distribution of the epithermal spectrum was observed for lattices in which the fuel-to-moderator ratio exceeded 1:2000.
