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 ?

Explanation

Much less, because in Thomson's model there is no such massive central core called the nucleus as in Rutherford's model.
