Nuclear Models and the Proposition
that Accelerated Charges Radiate
Electromagnetic Waves

Whenever a model of nuclear structure is proposed that involves rotation it is immediately confronted with the proposition that charged particles in orbits are subject to centripetal acceleration and accelerated charges radiate electromagnetic waves. Hence particles lose energy and the nucleus would collapse.

It is presumed that the proposition is valid and therefore the model cannot be valid. Here it is argued that proposition is not valid for real particles. The bases for this assertion are:


There is no real enigma concerning the absence of electromagnetic radiation for charged particles in atoms and nuclei. The Larmor formula would apply only to point particles and real particles are not point particles. They have charge distributed over a spatial region which may be small but it is not a point.
