Question 3 A spin ½ particle makes a transition from 2s (1 = 0) to 3p (1 = 1) orbital. The particle has an angular momentum I and a spin S. The total angular momentum of the particle is given by J = L + S (i) Show that S.L = L.Š (2) (4) (ii) Evaluate S. Z in terms of J², L² and S² (iii) Calculate the splitting between the 2s and 3p states using first order perturbation. [12]
