Question:

Suppose the perturbation takes the form of a delta function (in time):

assume that U_aa = U_bb = 0, and let U_ab = U*_ba Ξ α. If c_a (-∞) = 1 and c_b (-∞) = 0, find c_a(t) and c_b(t), and check that |c_a(t)|² + |c_b(t)|² = 1. What is the net probability (P_a→b for t → ∞) that a transition occurs?
