Consider a chain of radioactive decays 1 --> 2 --> 3 with nuclei of type 3 being stable (decay constants are 1 and
2).
(a) Assuming that at t = 0, N1 = N0 and N2 = N3 = 0, find Ni(t), I = 1, 2, 3.
(b) Examine Ni, I = 1, 2, 3 at small t, keeping only linear terms, and interpret the results
(c) Find the limits of Ni, I = 1, 2, 3 as t --> and interpret.
