Do we know any single photon (hard hard gamma rays) that have enough energy to convert (transform) to a neutron which do not have an electric charge?

So the number of particle (proton or neutron) is conserved according to your answer. I also have that impression, however, I have more questions. Sun radiates tons of energy as electromagnetic waves, these energy can be converted to mass according to e=mc^2 in principle. My question is: can...

mgb_phys, thanks for your prompt reply. I appreciate it, But it still not answer my question, I understand the relativity, that is, when you accelerate a particle, its mass increases, because you input energy to it. The energy is converted to mass according to e=mc^2. so depending on the...

During a nuclear reaction, some energy (or heat) radiate away, I understand that means some mass (or substance) get away. What left over is lighter. Does this mean some basic particle disappeared? for example there are less number of neutrons after the reaction? or the number of particles are...
