Homework Help: Rutherford scattering

  1. Feb 28, 2005 #1
    A) While reproducing the Rutherford scattering experiment in an advanced laboratory class, a student uses a gold foil with thickness 16.7 nm. The radioactive source emits a particles at 10.50 MeV, and the detector is placed at 24.5 cm from the target foil. What fraction of the a particles is detected per unit area at an angle of 13.6 degrees?

    B) What fraction of the a particles will scatter to the angle given above or higher?

    A .. fraction/area = N(theta) / Ni ...n = #/volume ...n = 5.90*10^22 ...dont really no where to go from here ... i have the equation Ntheta = Ni(n)(t)/16 r^2 (rmin)^2 1/(sin^4 theta/2)
