Exercise 6.20 The wave function of a hydrogenlike atom at time I = 0 is 1 /ll where gunfm (F) is a normalized eigenfunction (i.e., mm (P) = Rng(r)Y;m (6', 9.0)). (a) What is the timedependent wave function? (b) If a measurement of energy is made, what values could be found and with what proba bilities? (c) What is the probability for a measurement of 2 which yields lh? '1' (7', 0) = [ll/2,1719) #111,007) + ll/11,107) + W3,1,1(?)]
