Thus there were 23,000 spontaneous fissions per second. This means that the last few centimeters would have to be travelled in preferably much less than 40 microseconds. It is theoretically possible to build a plutonium gun-type device, but it would need to be 19 feet long in order to allow the sub-critical masses to be fused into a critical mass before a fizzle occurs. The mass of sound sample a plutonium gun-type device would have been beyond the payload of the B-29. After this problem was realized in 1943, work began in earnest on the implosion bomb, the "Fat Man". The gun-type method could still be used for highly-enriched uranium, though, and was employed in the "Little Boy" weapon which was used against Hiroshima, Japan. |

| At first it was thought that two pieces of sub-critical plutonium (Pu-239) could simply be shot into one another to create a nuclear explosion, and a plutonium gun-type design of this sort (known as the "Thin Man" bomb) was worked on for some time during the Manhattan Project.[3] However it was fat photo discovered that plutonium created for the bomb in the nuclear reactors at Hanford, Washington, even though it was super-grade weapon plutonium containing only about 0.9% Pu-240, was not as pure as the initial samples of plutonium developed at the cyclotrons fat photo at Ernest O. Lawrence's fat photo Radiation Laboratory in Berkeley, California. Because of the presence of the isotope Pu-240, reactor-bred plutonium had a much higher rate of spontaneous neutron emission than was previously thought, and if a gun-type device was used it would most likely pre-detonate and result in a messy and costly "fizzle". |
