May someone kindly advise on the Rutherford experiment? I have created a Gaussian of dP$_0$/$\Delta$$\theta$($\theta$), where P$_0$ is the number of counts of alpha particles through a 1.05X19.86 mm slit divided by the time elapsed and $\Delta$$\theta$($\theta$) is the angular width of the detector. At this stage the Au foil was not used, as this was merely the "background" measurement. I have integrated that Gaussian wrt $\theta$ between $-\infty$ and $+\infty$ to obtain the total P$_0$. However, this yielded a total P$_0$ equal to 24,000 counts/sec, which seems exorbitant and wrong. I'd be indebted for any help trying to figure out where the mistake is!
