EXAMPLE:
Nuclear Stopping Power for Protons in Silicon:

NOTE:
  • Output table and graph include the nuclear stopping power in units of Mev cm2/g (i.e., the mass nuclear stopping power).
  • Currently, the lower energy limit for Protons Nuclear Stopping Power is:
    • 1 keV for 1 ≤ Z < 46
    • 2 keV for 47 ≤ Z < 73
    • 3.5 keV for 74 ≤ Z ≤ 92
  • Nuclear Stopping Power for compounds can be determined by means of Bragg's rule, i.e., the overall Nuclear Stopping Power in units of MeV cm2/g (i.e., the mass nuclear stopping power) is obtained as a weighted sum in which each material contributes proportionally to the fraction of its atomic weight. An example for selection, with water (H2O) as target, follows:
