Photons and particle interaction

In summary, the conversation discusses the potential interaction of radiation with matter in a hypothetical place where atoms have no electrons. The participants suggest that there may not be any well-known effects such as the Compton effect or photoelectric effect, but nuclear fission or fusion could still occur. One person mentions the possibility of particles without electrons in the moments after the Big Bang, and suggests researching this further. Another person brings up the idea of using certain nuclides as an energy source.

I wonder how the radiation will interact with matter on a hypothetical place where the atoms have no electrons. Will the photons and particles will interact with matter to produce any effects like that on earth.

I don't think there will be any compton effect, photoelctric effect, pair production, ionization etc. Only effect i could think of is nuclear fission or fusion.
Anyone else has any thoughts on this ?

I'm pretty sure that momments after the Big Bang, there were particles without electrons, do to the extremely high amount of energy. Maybe read some books on that, or conduct a query on google.

Some nuclides have excited states. There has been some discussion about Hf-172 being used as an energy source this way.
 

1. What is a photon?

A photon is a fundamental particle that makes up electromagnetic radiation, including visible light, radio waves, and X-rays. It has no mass and travels at the speed of light.

2. How do photons interact with matter?

Photons can interact with matter through three main processes: absorption, scattering, and emission. In absorption, a photon is absorbed by an atom or molecule, transferring its energy to the particles. In scattering, a photon changes direction when it encounters matter but does not lose energy. In emission, a photon is released by an atom or molecule, often after being excited by another photon or energy source.

3. What determines the energy of a photon?

The energy of a photon is determined by its frequency or wavelength. The higher the frequency or shorter the wavelength, the greater the energy of the photon. This is described by the equation E=hf, where E is energy, h is Planck's constant, and f is frequency.

4. Can photons interact with each other?

While photons do not have mass, they can still interact with each other through processes such as the creation and annihilation of virtual particles. However, these interactions are incredibly rare and typically only occur in extreme conditions, such as in high-energy particle collisions.

5. How do particles interact with each other through the exchange of photons?

In quantum field theory, particles can interact with each other through the exchange of virtual particles, including photons. This process involves particles emitting and absorbing virtual photons, which mediate the interaction between the particles. This is known as the electromagnetic force and is responsible for interactions between charged particles.
