摘要：
Based on a consistent quantum-mechanical approach, we calculate and analyze the suppression of the polarization bremsstrahlung (PB) from a fast charged particle moving in an amorphous medium. The suppression effect is attributable to destructive interference between the contributions from atoms of condensed material to the bremsstrahlung due to their finite sizes and chaotic arrangement. We calculate the spectral and angular PB dependences on various targets that demonstrate characteristic features of the phenomenon under consideration. We have established the region of the clearest manifestation of the suppression effect. The results obtained by various methods of calculation are compared.
