THEORY OF SPONTANEOUS RADIATION BY BOSONS IN QUASI-CLASSICAL TRAJECTORY-COHERENT APPROXIMATION

The first order quantum correction is obtained for the characteristics of spontaneous radiation as a functional of a classical trajectory by means of quasi-classical trajectory-coherent states method for relati vistic spinless particle in an arbitrary external electromagnetic fiel d. It is shown that the power of boson radiation coincides up to O(h2B AR), hBAR --> 0 with the power of electron radiation averaged over spi n states calculated by the TC-states of the Dirac equation. Certain sp ecific examples are considered on the base of & general formula for th e radiation power in the non-relativistic approximation, in particular , an expression for the radiation power in an axially symmetric magnet ic field is obtained.
