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 (-5[1])in the liquid drop model. (10[2])Lise Meitner (“LEE-zuh MIGHT-ner”), who co-discovered (10[2])this process, was snubbed from the (-5[1])Nobel Prize awarded to Otto Hahn. (10[1])Graphite control rods moderate this process (10[1])by emitting neutrons. (10[1]-5[1])A chain reaction of this process occurs at the critical mass for (10[1])uranium-235. For 10 points, name this process in which a heavy nucleus splits into smaller ones, (10[2])contrasted with fusion. (10[1])■END■
