Hey. I've just conducted Rutherford's gold foil scattering experiment and am a little stuck on a part of the analysis. One of the objectives of the lab script is;
'To correct the counting rates measured in one plane for the fact that the foil scatters in a 3D cone'
So the detector only detects alpha particles in a line and doesn't account for others scattering above and below it. I've plotted the count rate as a function of the angle measured with the detector, how will this correction scale my results and how do I calculate this scaling factor?
The Attempt at a Solution
I attemped using a solid angle formula but got again stuck with not knowing the dimensions.
