Obtaining range from bethe-bloch formula

  1. Dec 26, 2009 #1
    While studying particle physics, i saw that the range formula is the integration dE/(dE/dx) but as you know that there are no variable E in the formula. how could that integration be done?

    well i think we can do it by ourselves and we must use a programming language and i think the trapezoidal rule would be useful to solve that.

    But i could not find out how could that integration be done please help me. thank you

    But there is a velocity. From velocity you can get energy.

    Look at Equation (1) and Figure 1 in

    Eq (1) is the Bethe Bloch energy loss equation for protons. The independent variable is β. The integrated range is obtained by iteration of

    dx = dE/[dE/dx]
