The reaction would probably die out before much of the material had a chance to react, and thus the bomb would not be very destructive. It might be much better, says the author, to surround the uranium detonator with lithium hydride. When hydrogen and lithium atoms in this common chemical compound are given sufficient energy, they react with one another, forming two atoms of helium 4. It takes only 100,000 electron volts, says the article, to start the reaction. Each atomic collision yields...
