WebA boosted fission weapon usually refers to a type of nuclear bomb that uses a small amount of fusion fuel to increase the rate, and thus yield, of a fission reaction. The neutrons released by the fusion reactions add to the neutrons released due to fission, allowing for more neutron-induced fission reactions to take place. The rate of fission is … WebApr 4, 2013 · In this Letter, we map the relation between stacking geometry and SF yield in crystals based on perylenediimide (PDI) derivatives.
