Suppose you are given a chance to repeat the alpha-particle scattering experiment using a thin sheet of solid hydrogen in place of the gold foil. (Hydrogen is a solid at temperatures below $14\; K$.) What results do you expect?

Option A

Option B

Option C

Option D

Solution

In the alpha-particle scattering experiment, if a thin sheet of solid hydrogen is used in place of a gold foil, then the scattering angle would not be large enough. This is because the mass of hydrogen is less than the mass of incident $\alpha$ – particles Thus, the mass of the scattering particle is more than the target nucleus (hydrogen). As a result, the $\alpha$ particles would not bounce back if solid hydrogen is used in the aparticle scattering experiment and so we cannot determine size of the hydrogen nucleus.
