Bremsstrahlung of a vector particle in the nuclear field

A differential cross section of bremsstrahlung radiation of a vector particle in the Coulomb field of the atom nuclei is calculated in the Born approximation. The calculation of the differential cross section of the V1-+(Ze)→(Ze)+V2-+γ effect was carried out by the Feinman method. All process particles were supposed to be nonpolarized. With the help of integration obtained was the spectral distribution of photons in non-relativistic and of superrelativistic ranges of particle energies
