text: Correcting for experimental error, Geiger and Marsden found that the number of alpha particles that are deflected by a given angle Φ is indeed proportional to csc4(Φ/2).
text: Geiger and Marsden found that the number of scintillations that appeared on the zinc sulfide screen was indeed proportional to the thickness as long as said thickness was small.
text: (Geiger and Marsden knew that for foils of equal stopping power, the number of atoms per unit area is proportional to the square root of the atomic weight).
text: They found that, within the range of experimental error, that the number of scinitillations was indeed proportional to 1/v4.
text: First, the number of α particles scattered through a given angle should be proportional to the thickness of the foil.
text: Second, that number should be proportional to the square of the nuclear charge.
