Credit to this invention usually goes to Lawrence Livermore Lab's Samuel Cohen in 1958. The ERW was tested in 1963. Development was halted by President Carter in 1978 and restarted by President Reagan in 1981. Some weapons were retired in 1992 by President George Bush. The last warhead was dismantled in 2003.
Leonardo's inventions were much more meaningful than that. See the related link.
The neutron is a part of the atom, therefore it is smaller.
Ernest Rutherford described the existence of the neutron.
electron and neutrino are formed by the decay of neutron.
A glass with the composition CdO-SiO2-B2O3 forms a neutron absorbing glass which is quite stable against moisture attack and divitrification and are good slow neutron absorbers
the neutron bomb was called as capitalist bomb because it destroyed people not property
Uncontrolled neutron chain reaction, invented in 1933 by Leo Szilaard, implemented in 1945.
Neutron bomb
No one invented the neutron. It was discovered by James Chadwick.
USA
The Hydrogen Bomb .
As he did not have to build the atomic bomb, all that he had to do to invent the atomic bomb was to think.That is really all that is required for most inventions: think of a new and novel way to do something.What Leo Szilard invented that was new and novel was the neutron chain reaction, the process that in the atomic bomb drives the exponentially accelerating nuclear fission of uranium or plutonium atoms. However he did not know about either nuclear fission or what elements might be able to support the neutron chain reaction process that he invented. This took the work of others before the atomic bomb could actually be built.
The United States was the first country to develop the neutron bomb in the 1950s and 1960s. The neutron bomb is a type of thermonuclear weapon designed to release a large amount of deadly neutron radiation while minimizing blast and heat effects.
Leo Szilard invented the fission bomb. Edward Teller invented the fusion bomb. Both were from Hungary.
The first bomb was invented in 1281 A.D.
he invented the dynamite or the atom bomb
