Main Question or Discussion Point
Does a moving neutron have an electric field ?
In order to get radiation emission from a moving charge, the charge needs to accelerate. Then you get synchrotron radiation. I would guess, but I might be wrong so be careful, that the same is valid for a magnetic dipole such as the neutron. However, the effect must be monstrously small.so then if a moving neutron has a small E field and B field then we could get photon emission from it , is this correct .
