(c) For a small thickness T, keeping other factors constant. It has been found that amount of alpha particles scattered at direct angles is proportional to T. This linear dependence implies?

(d) To calculate average angle of scattering of alpha particles by thin gold foil, which model states its wrong to skip multiple scattering?

Answer –

(c) Single collisions give rise to the dispersing phenomenon. The probability of a single collision is directly proportional to the amount of target molecules. And since the number of target particles increase with an expansion in thickness, the impact likelihood depends directly on the thickness of the objective.

(d) Thomson’s model

Multiple scattering in Thomson’s model should not be disregarded in order to figure out the average scattering angle of alpha particles by a thin gold film. This can be established on the grounds that almost no deflection is caused by a solitary collision in this model. Subsequently by considering multiple scattering, the watched normal scattering edge can be clarified.
