A Plotting a Bragg Curve in SRIM

[rphys]

I'd like to plot a Bragg curve for an alpha particle in air.

I'd like to make one plot for ²³⁹Pu (5.156 MeV alpha) and one plot for ²³⁸U (4.267 MeV).

Does anyone know how I can do this? I would like a basic plot of stopping power (MeV/cm) vs path length (cm).

Thank you

It isn't a Bragg curve, but by clicking the "stopping range / tables" feature I can get the range data for the alpha particle (below). The only problem is I can only seem to input an element (e.g. helium) and not an alpha particle itself. Is 37.60 mm about right for a 5.156 MeV helium / alpha particle in air?==================================================================
