Part of this work was supported by the INTAS contract 97-30392: "Theoretical Investigation of Propagation of Particles, Ions and X-Rays through Straight and Bent Nanotubes and Associated Phenomena". Two of us (G.B. and T.Q.) took part in this work during training periods at Institut de Physique Nucléaire de Lyon.

Radiation reaction is revisited, first in a new classical approach, where the physical particle 4-momentum is redefined as the energy-momentum flux across the future light cone and is not parallel to the 4-velocity. Then in a semi-classical approach, it is shown that, when emitting a photon, the particle "side-slips" transversally to its initial momentum, justifying the non-collinearity between momentum and mean velocity. Side-slipping is finally checked in a pure quantum mechanical treatment of synchrotron radiation.
