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 (10[1])(“LEE-zuh MIGHT-ner”), who co-discovered this process, was snubbed (10[1])from the Nobel Prize (10[1])awarded to Otto Hahn. (10[1])Graphite control rods moderate (10[1])this process by emitting neutrons. (10[1])A chain (10[1])reaction of this process occurs at the critical mass for uranium-235. (10[1])For 10 points, (10[1])name this process in which a heavy nucleus splits into smaller ones, contrasted with fusion. ■END■
