Determine and plot for 5 keV to 100 MeV the fraction of the total cross section due to each of the four interaction processes for
(a) hydrogen,
(b) nitrogen,
(c) aluminum, and
d) lead.
Use the excel data file and use logarithmic scales for the energy (x-) axes. Make four plots corresponding to the 4 elements and on each plot have four graphs corresponding to the four interaction processes.
