✦ Synopsis

We show that the energy-momentum tensor for the massless fields generated by a multipolar source, confined to a world-line, can be split into a radiation and a bound part, both of them having zero divergence off the source world-line. This allows us to compute in a simple way the energy of radiation emitted by the source. Scalar, vector, and tensor fields are studied. An exact expression for the radiated energy of a spinning electron is exhibited. By analizing a system of two electrons we show that radiation from extended sources cannot be described locally in the manner mentioned above.

Orthogonal coordinate systems with helical geometry are constructed in euclidean 3-space and the Schriidinger equations in these coordinate systems are obtained. Of the two helical coordinate systems discussed, the external system consists of flat surfaces while the internal system consists of surfa
