Round 8: Tossup 3
A substance’s ability to undergo this process is roughly proportional to “Z-squared over A.” The reproduction factor and resonance escape probability appear in Fermi’s four-factor formula describing this process. This process is analogized to a water droplet splitting down the middle in the liquid drop model. Lise Meitner (“LEE-zuh MIGHT-ner”), who co-discovered this process, was snubbed from the Nobel Prize awarded to Otto Hahn. Graphite control rods moderate this process by emitting neutrons. A chain reaction of this process occurs at the critical mass for uranium-235. For 10 points, name this process in which a heavy nucleus splits into smaller ones, contrasted with fusion. ■END■
