X-ray damage assessment of bR. (a) The difference Fourier map between the first (0.01 MGy) and damaged (0.45 MGy) datasets at 100 K. The positive (+4σ) and negative (−4σ) densities are represented as green and red meshes, respectively. (b) The difference Fourier map between the first (0.01 MGy) and damaged (0.45 MGy) datasets at 15 K. The positive (+4σ) and negative (−4σ) densities are represented as blue and pink meshes, respectively. (c) Changes of the damage ratio at 100 K (red) and 15 K (blue) as a function of the doses. Single exponential functions fitted to the occupancies are indicated as solid lines.
