Thee Role of Enrico Fermi andEarly Neutron Experiments

Enrico Fermi, working in Rome in thee early 1930s, systematycally bombarded elements with neutrons. He discrevered that slowingg neutrons down with a moderator (such as parlastn wax or water) dramatically increaged their efficiency in inducing nucler reactions.

Within weeks, fizycy ahound thee eterd, including ding Niels Bohr, Enrico Fermi, and Leo Szilard, grapped the implications. If a fission reactionn released neutrons, those neutrons could split more uranium atoms in a chain reaction. The possibility of explosive or controlled energy release was no longer theritical. This realizationset off a scramble among nations to harness the atom - first for war, and later for peace.
