Differential cross section for Compton-scattered photons on DNA (in barn per stereoradian) for a linearly polarized X-ray beam of 64 keV as obtained with Monte Carlo simulations [using Geant4 (Agostinelli et al., 2003)] and tabulated values (Hubbell et al., 1975) (dashed lines), for different azimuthal regions: ϕ = [0–10]° (green), ϕ = [85–95]° (blue) and integrated over ϕ (red). ϕ indicates the angle relative to the direction of the polarization vector. |
