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?

Verified by Experts

The nucleus of a hydrogen atom is a proton. The mass of it is `1.67 xx 10^(-27)` kg, whereas the mass of an incident `alpha`-particle is `6.64 xx 10^(-7)` kg. Because the scattering particle is more massive than the target nuclei (proton), the a-particle won.t bounce back in even in a headon collision. It is similar to a football colliding with a tennis ball at rest. Thus, there would be no large-angle scattering.

Answer the following questions, which help you to understand the difference between Thomson's model and Rutherford's model better. a. Is the average angle of deflection of a-particles by a thin gold foil predicted by Thomson's model much less, about the same, or much greater than that predicted by Rutherford's model? b. Is the probability of backward scattering (i.e., scattering of a-particles at angles greater than 90^@ ) predicted by Thomson's model much less, about the same, or much greater than that predicted by Rutherford's model? c. Keeping other factors fixed, it is found experimentally that for small thickness t, the number of alpha - particles scattered at moderate angles is proportional to t.What clue does this linear dependence on t provide? d. In which model is it completely wrong to ignore multiple scattering for the calculation of average angle of scattering of alpha particles by a thin foil?

Given below are densities of some solids and liquids. Give rough estimates of the size of their atoms : [Hint : Assume the atoms to be 'tightly packed' in a solid or liquid phase, and use the known value of Avogadro's number. You should, however, not take the actual numbers you obtain for various atomic sizes too literally. Because of the crudeness of the tight packing approximation, the results only indicate that atomic sizes are in the range of a few Å].
