For the examples in Problem 11.24 (c) and (d), calculate C_m(t), to first order. Check the normalization condition:

and comment on any discrepancy. Suppose you wanted to calculate the probability of remaining in the original state Ψ_N; would you do better to use

Problem 11.24 (c) and (d)

(c) For example, suppose Ĥ' is constant (except that it was turned on at t = 0, and switched off again at some later time . Find the probability of transition from state N to state M (M ≠ N), as a function of T.

(d) Now suppose Ĥ' is a sinusoidal function of time: Ĥ' = VCos(ωt). Making the usual assumptions, show that transitions occur only to states with energy EM = EN ± ћω, and the transition probability is
