Collisional redistribution of radiation. III. The equation of motion for the correlation function and the scattered spectrum
Abstract
Computations were made of the scattering of monochromatic radiation by a degenerate atom in the binarycollision approximation for field strengths whose products of the Rabi frequency for atomic transition and the duration of a strong collision are much less than 1. An expression of motion for the correlation function is derived which does not exclude the region where thermal correlations may be neglected; the equation is valid outside the quantumregression regime, and has a straightforward solution for practical cases. Solutions for the weakfield linear response regime are presented in terms of generalized absorption and emission profiles which depend on the indices of the atomic multipoles.
