Of course a particle moving within a magnetic or electric field emits radiation due to acceleration. This is the normal behavior and I was specifically referring to the case where nothing else was around to interact with the particle. No external fields means no radiation for a single particle. Combinations can radiate if their spin states can be lowered in net energy.

In reply to David Roberson's message of Sat, 9 Aug 2014 13:15:37 -0400 (EDT): Hi, >That is the model that I try to understand Axil. But I do not believe that an isolated single moving particle can emit thermal energy directly. ...unless it happens to be in a magnetic field, in which case it can emit cyclotron radiation. > A free proton moving uniformly in space has a relative velocity to every observer except one at rest to it. It therefore can not emit thermal energy in the form of IR without the interaction of other particles around it. The infrared photons contain energy that once existed as kinetic energy(thermal) of the system of particles. Gravitational energy, of course, can end up as photon energy when a cloud of hydrogen gas and dust condenses. > >Dave [snip] Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
