Fission is the activity of destabilizing the nuclei

What is  Fusion?
Nuclear physics are sub-disciplines of physics, which are based on physical examination of the interactions of atoms with each other or separately. Of course, as a sub-discipline of physics, there are common points with other sub-disciplines of physics. For example, for Bohr to find the quantum condition, the electron in the orbital state is assumed to be wavy, and for the angular momentum (L) classical physics is used as the "r x p". There are numerous such interactions.

Fission is the activity of destabilizing the nuclei (Z> 82) by aggravating the nuclei (Z> 82). This unstable atom becomes radioactive (or already radioactive) and is eaten and divided by the coloumb force due to the high core load. This is where the energy is released and this is a roughly working way of atomic bombs. As a result of the fission, an average of 2.5 neutrons is released very rapidly. The oscillating neutrons aggravate the other nuclei and drag it to the chaining. These neutrons are sufficiently controlled (if the neutron replication factor (net neutron increase passing through the next generation) = 1) becomes a controlled chain reaction and the nuclear reactors process this way. If they do not slow down (neutron replication factor (net neutron increase leading to the next generation)> 1) uncontrolled nuclear reaction. So the atomic bomb. (This situation applies to uranium -238. Unlike carbon uranium, it cools more slowly neutrons.) Uranium -238 slow neutron can also absorb, but usually (Chernobyl exception) can not fission. If the neutrons cannot be slowed down, the reaction stops because the uranium-238 cannot release enough neutrons. This means that nuclear reactors are generally safe. However, in uranium-238.Atom used uranium -238 value of uranium-238.Atom bomb uranium -235 value should be decreased and uranium -235 value should be increased.

What is fusion?
The fusion (Z <56) is more than the energy obtained by the fission of the nuclei, which is possible by the fusion of the nuclei possible for non-heavy kernels. Why do we use fission instead of fusion? Because the fusion is not yet under control. The reason is that the hydrogens' core charges repel each other. There are 3 suggestions for fusion. The first one is called Tokamak. H is used at low density. The Hars found in the medium (gas heated too) throw away their electrons. In the other method, the laser is used to give big energy to small objects. H's are detonated in a controlled way. The other is cold fusion. This method uses a (-) charged particle called muon. Muon may stick to the core when slowed. The muon that clings to the nucleus destroys the surplus of the proton so that the hydrogen nuclei attract each other. The energy released expels the muon, and so on. But this method did not work because the muo did not stick again.

Fusion is a very important and clean energy source. Many studies are in progress. For example, US arms company Lockheed Martin appears to have fallen considerably on this issue.
