The electrons are not repelled by the nucleus and are not affected by the strong force.
Most of the electrons will travel straight through the gold foil and some will be deflected, as with alpha scattering. However, due to the particle-wave model, electrons can also behave as waves. This means that the electrons are also diffracted. The greatest diffraction occurs when the wavelength of the electrons is close to the size of the nucleus.n
nλ = dsinθ for a maxima
λ/2 = dsinθ for a minima
This can allow us to calculate the diameter of the nucleus, and is elastic scattering.
The average energy for these electrons is 300MeV.
Due to the high energy of the electrons, the relativistic factor applies.
γ = Etotal/Erest
To find the radius of a nucleus, you can use the formula r = r(o)A^1/3
Where r(o) is the radius of a single nuclei, a constant.
