![Line and scatter plot titled with y-axis “MACS [mb]” and x-axis “kT [keV]”. A black curve labeled KADoNiS decreases steadily from upper left to lower right. It's surrounded by a gray shaded band (CERN n_TOF ±1σ_stat), a narrower red shaded band (CERN n_TOF ±1σ_sys), and blue (ENDF/B-VIII.1), green (JEFF-4), and orange (TENDL-2025) curves that follow similar declining trends. Scattered data points represent data from earlier studies: an orange pentagon (J. Holmes 1976), red square (M. Harris 1981), black circle (T. Rauscher 2000), blue star (S. Goriely 2002), and gray diamond (S. Goriely 2005).](https://pbs.twimg.com/media/HQPpHEuWwAAg8Bm?format=webp&name=small)
