Statistical properties of resonance radiation of selectively reflected from semi-infinite medium

The problem dealing with quantum-statistical properties of resonance radiation reflected selectively from undistributed media in case when the photons within the studied radiation flux are mutually correlated is formulated and solved. The accounting of the photon mutual correlation does not allow in principle to approach the problem using the methods of the theory of perturbations. The quantum image of the optical theorem of amorphization making the infinite subsequence of the Feynman diagrams vanish is presented. Frequency and angular distribution of quanta in the reflected flux and the effect of suppression under reflecting of laser source radiation are predicted
