Is the probability of backward scattering (i.e. scattering of a-particals at angle greater than `90^(0) )` predicated by Thomson's model much less, about the same , or much greater than less, about the same , or much greater than that predicted by Ruthorford's model ?

Text Solution

Verified by Experts

Much less, because there is no such massive core (nucleus) in Thomson.s model as in Rutherford.s model.

Answer the following questions, which help you understand the difference between Thomson’s model and Rutherford’s model better. (a) Is the average angle of deflection of -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 alpha -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?
