what exactly happens during a neutron-neutron,proton-neutron and neutron proton collision??

[Iota]

Nuclear fission or fusion, maybe nothing. Depends.

 

Here's the little amount I know about nuclear fusion:

When two protons fuse together energy is released. According to Einstein's E=mc², mass is lost in the form of energy; two non-fused protons have more mass than two that are fused together.

Most collisions will be scattering. It takes a lot of energy (like in the interior of the sun or in the LHC) to produce more complicated reactions.

Without electrostatic force barrier(++ or - - ), particles could be easily fused by nuclear force.

Fission with two nucleons, that would be new.

 

Fusion between two neutrons has never been seen and this still needs an explanation. Between two protons, it never produces a di-proton (whose mass is hence unknown), which also remains to be explained.

 

Mass is energy whatever the form of energy: it can be speed, chemical energy, height, heat... In a dam, water loses mass which is converted into electricity in the turbine and the alternator. In fusion, the strong force releases energy available for instance in a neutron's speed, while in fission, electrostatic repulsion releases energy available in the fragments' speed.

 

Because nuclear energy is more concentrated, the mass variation is more perceptible and such figures get practically usable. That's all about mass variation.

 

In a collision at higher energy like at the LHC, nearly anything can happen (mainly particles production), and the result depends much on the collision energy and very little on what the initial particles were.

If particles get over the electrostatic barrier, the particles are easily fused by nuclear force. And then, they will go decaying or maintaining their structure depending on their energy state in the nucleus .

Two proton binding state is very unstable, so it can easily decay into other particle composition.

Why do you feel the need to give some sort of explanation, just as if Nature had to obey to your understanding?

 

The absence of a di-neutron is still an open question within the existing theories. Same for the di-neutron.

There is a stability chart about atom. Fe is the most stable atom.

But I have not found the equation about the nuclear stability yet.

A paper tried to solve this problem by using electron charge stability in the nuclear.

Neutron stability give us some doubt about the origin of the atom.

You should make a very clear mental difference between science and pseudo-science as in some links you give.

[alpha2cen]

Stability chart is correct. The remainders are in progress.

nothing spectacular. The high energy enough collisions in the lab do create fascinating stuff though.

 

 

Daily, protons hit other protons in interstellar space
