Note that the sin θ term suppresses the cross section at θ = 0 and θ = π as it had done<br />
for the expression for the cross section for coherent scatter.<br />
So the final thing that we need <strong>to</strong> do is integrate over θ <strong>to</strong> obtain a <strong>to</strong>tal cross section<br />
which is equal <strong>to</strong> this quantity. We see here σ 0, which is the cross section for<br />
coherent scatter, and then we see a lot of fac<strong>to</strong>rs involving α, where α is related <strong>to</strong><br />
the energy of the pho<strong>to</strong>n beam.<br />
