Comparison of root-mean square (RMS) values of scattering angles (in [mrad]) between semi-empirical calculations and simulated values for muons in various target materials with a thickness of 1 mm. The top figure shows values derived from the simulation (symbols) and compares them to calculated values based on a semi-empirical approach (solid lines). The red curve (boxes) shows the results for uranium dioxide, the orange curve (circles) corresponds to polyethylene, the blue curve (pentagons) corresponds to stainless steel, the green curve (up-pointing triangles) corresponds to ductile iron and the violet curve (down-pointing triangles) corresponds to zirconium alloy. The lower five figures show for each material therelative deviations between simulated and calculated values.
