“…The findings suggesting the superiority of the RMFF theory have been reported earlier [16,19,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. It has been established both from comparison of theoretical results and from experiments that the RMFF, in general, produces better results than other choices of the FF [34].…”

Polarization transfer in Rayleigh scattering of hard x-rays

“…At even higher energies, scattering from vacuum fluctuations in the atomic field (Delbrück scattering [37]) and nuclear scattering [3,15] become important. Comprehensive reviews on the topic of elastic x-ray scattering by atoms have been given by Kane et al [23] in 1986 and Bradley et al [5] in 1999.…”

Calculation of the total Rayleigh scattering cross sections of photons in the energy range of 30–50keV for Nb and Mo elements

“…It has been shown by Bradley and Ghose (1986) that the differential Rayleigh scattering cross section values obtained by using the MRFF approximation are considerably smaller than the values obtained by applying the RFF and NFF approximations, and closer to the experimental data. It was mentioned (Bradley and Ghose, 1986;Bradley et al, 1999a;Kane, 2005;Kane et al,1983) that the RFF approximation is seen to be inadequate for an explanation of experimental data while the MRFF approximation is better than RFF approximation and in agreement with experimental data, and the NFF approximation is closer to the experimental data than RFF calculations. It has been a general experience that the order of validity of form-factor approximations is MRFF, followed by NFF, with RFF yielding the poorest predictions.…”
