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 (10[1])drop model. Lise (10[1])Meitner (“LEE-zuh MIGHT-ner”), who co-discovered this process, (10[1])was (10[1])snubbed from the Nobel Prize awarded to Otto Hahn. Graphite control rods moderate (10[1])this process (10[2])by emitting neutrons. (10[2])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■
