The absorption cross-section of these entities is inversely proportional to the square root of their energies in the "one over nu" region.
The absorption cross-section of these entities is inversely proportional to the square root of their energies in the "one over nu" region. The reproduction factor and the probability of these entities escaping resonance capture appear in the four-factor formula for their "multiplication factor." Whether these particles' energies are below 1 eV, between 1 eV and 10 keV, or above 10 keV determines whether they are "thermal," "epithermal," or (*) "fast." Graphite and heavy water-based "moderators" reduce the energies of these particles, three of which are produced when uranium reacts with one of them to form rubidium and cesium, thus causing a chain reaction. Nuclear fission reactions are induced by, for 10 points, what uncharged particles found in atomic nuclei?
