Particle to particle elastic collision possible?

[alpha2cen]

When a particle collide with a particle, we think that elastic collision, annihilation or scattering is possible. Is particle change it's shape against external stress? Does Particle itself have elastic property?

In reality, a particle isn't really a ball, but rather a probability wave which has quantized states. The shape can change depending on the collision by changing the quantum state by changing the momentum which creates very specific shapes, and sometimes different types of refraction can occur. Also, because of the wave nature of particles, there's no finite point where you can say the particles collided, all you can say is when the magnetic repulsion becomes too strong for the momentum of a particle in a collision to to carry the particle any closer to the other particles.

Essentially, even though electron sub-shells can move about an atom to create isomers, the general shape of different particles don't have this sort of soft rubber response that stretches and compresses them in different areas, they like to keep their shape.

Elastic collision/scattering just means the exact same particles come out pf the interaction as went into it, but with different momentum and energy.

That's ALL that it means. It doesn't infer any particular mechanism of scattering.

To make elastic collision this condition must be satisfied.

How about this picture?

I think that you are approaching this classically, and that will cause problems. The idea that a particle can deform means there are allowed vibrational states within that particle, which could presumably relax via photon emission, meaning the collision is not elastic. It also means you are not talking about fundamental particles, like electrons or quarks, which are point-like.

In an elastic collision the energy is conserved within the two particles.

In a non elastic collision a photon would take away some of the energy,therefore the energy is not conserved within the two particles.

Without contacting between two particles, we can say it "collision"?

Where is the energy storing place in the electron or so?

Yes. Also scattering.

There will be potential energy because of the location of the charges.
