Applied sciences






















The Bethe-Feynman efficiency formula, a simple method for calculating the yield of a fission bomb,[1] was first derived in 1943 after development in 1942. Aspects of the formula are speculated to be secret restricted data.[2]

Related formula[edit]

  • a = internal energy per gram
  • b = growth rate
  • c = sphere radius

a \approx (bc)^2  f

A numerical coefficient would then be included to create the Bethe–Feynman formula—increasing accuracy more than an order of magnitude.[3]
