Photons production in dense matter

The bremsstrahlung of the charged particles interacting in the dense medium is studied on the basis of the diagram formalism for the Green two-particle functions. The exact expressions for the Green two-particle functions responsible for the particles bremsstrahlung process are obtained for the case of the soft photons production in the matter. The identified Green functions are determined completely by totality of the closed irreducible diagrams. It is shown that the particles coherent multiple scattering in the case of the bremsstrahlung in the sufficiently dense medium in the spectrum far-away long-wave area leads to the additional quenching of the bremsstrahlung photons yield
