SPIN LIGHT

The spin magnetic moment of an electron moving in an homogeneous magne tic field is a source of electromagnetic radiation. It:is interesting that this radiation (spin light) manifests itself at high electron ene rgies and can actually be measured in modern electron accelerators. Th e problem of identification of the spin radiation against the backgrou nd of powerful synchrotron radiation, recoil effects, and other relati vistic phenomena are considered. The relativistic neutron is considere d as a source of pure spin radiation. The correspondence principle for spin radiation, with and without spin flip, is formulated.
