(Color online) Small angle CXS: Effect of thermal flexibility on angular correlated X-ray scattering around the Bragg ring at q = 0.05 nm⁻¹ in 294 bp long (L = 100 nm) DNA molecules modeled as worm-like chains with persistence lengths, l_p. Scattering calculations are averaged over 30,000 molecular fluctuations generated by equilibrium Monte Carlo simulations. The correlator is normalized to its value at 0 radians to show the relative prominence of the peak. A soft X-ray beam energy of 124 eV was assumed for projection onto the two-dimensional detector.
