    Need to fourier transform to momentum space, i.e.

     \psi(p) = \frac{A}{\sqrt{h}}\int^\infty_{-\infty}xe^{-\alpha x^2} e^{\frac{-ip}{\bar{h}}} dx

    Evaluate this integral and then you have an expression for p, hance can find dp.

    See http://quantummechanics.ucsd.edu/ph1...es/node82.html for further info!
