Radiation & Rutherford

The relation between the sizes of electrons .02 angstroms, Gold Nucleus 10-5 angstroms, and the radius of the atom .5 angstroms.

Very important, we learned about alpha – e^2/4 pi epsilion nought h-bar c, this was called the infinitesimal constant? Didn’t quite catch the name.

So Rutherford was looking at alpha particles, and he was shooting the Helium 4 particles at a thin sheet of gold.

We calculated and equation for knowing the certain number of electrons, which would have their path bent by columbs law and hit at a certain angle of a "ring". To help with this we learned how to calculate solid angles.
