Integrating the Bethe-Bloch Equation to Find the Range

  1. Dec 15, 2011 #1
    My question is taking the Bethe-Bloch equation and integrating to find the range of an energetic Deuteron. I first have the Bethe-Bloch equation,

    [tex] \frac{dE}{dx} = -\rho 0.1535 \frac{Z_{p}^{2}}{\beta^{2}} \left(\frac{Z_{A}}{A}\right) \left[ln\left(\frac{2 M_{e} c^{2} \beta^{2}}{IE\left(1 - \beta^{2}\right)}\right)^{2} - 2\beta^{2}\right] [/tex]

    To find the Range we integrate the following equation,

    [tex] \mbox{Range} = \int_{E}^{0} \frac{1}{dE/dx}dE [/tex]

    I have tried to integrate this equation but I am unable to get it to work. My integral looks like the following,

    [tex] \mbox{Range} = \int_{E}^{0} \frac{1}{\frac{1}{E}\left(ln\left[\frac{E}{\left(1-E\right)}\right]^{2} - 2*E\right)}dE [/tex]

    Where [itex] \beta [/itex] is a function of Energy. What am I doing incorrect?
    TIA
