Sažetak
In this work we calculate intensity for inelastic scattering of radiation from electron-positron bound state (Positronium atom). Because the scattering occurs from two centres, scattering intensities exhibit interference patterns, which depend on the energy of incident radiation. For small incident energies (large wavelengths of radiation compared to the mean radius of Positronium atom) the interference term gives an important contribution to the scattering process. In this case radiation demonstrates a wave nature. For high incident radiation energies (small wavelength compared to the mean radius of Positronium atom) we show that the interference term is negligible and scattering process goes s a direct scattering of photon from electron or positron separately. Here radiation demonstrates particle nature.
