Tossup

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. (10[1])Lise Meitner (10[1])(“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 (10[1])by emitting neutrons. (10[1])A chain reaction of this process (10[2])occurs at the critical mass for uranium-235. (10[1])For 10 points, name this process in which a heavy nucleus splits into smaller (10[2])ones, contrasted with fusion. ■END■
