  The sigma-omega model in mean-field approximation where the meson fields are
treated classically, describes much of observed nuclear structure and has been
employed to describe the nuclear equation of state up to the quark-gluon phase
transition. The acceleration of the meson sources, for example, in relativistic
heavy-ion collisions, should result in bremsstrahlung-like radiation of the
meson fields. The many mesons emitted serve to justify the use of classical
meson fields. The slowing of the nuclei during the collision is modeled here as
a smooth transition from initial to final velocity. Under ultra-relativistic
conditions, vector radiation dominates. The angular distribution of energy flux
shows a characteristic shape. It appears that if the vector meson field couples
to the conserved baryon current, independent of the baryonic degrees of
freedom, this mechanism will contribute to the radiation seen in relativistic
heavy-ion collisions. The possible influence of the quark-gluon plasma is also
considered.
