54. From the states of j = and j = obtained by combining the states of f = 1 and s = states (a) Determine the expectation values of L. S for the states |j = 3/2, m; = 3/2), |j = 3/2, m; = 1/2) and ||j = 1/2, m; = 1/2). (b) For these states, what is probability that a measurement of S, yields 1/2 2S+1 h 55. List the possible spectral terms L, resulting from the following two electron configurations (ns n' s), (ns n' p), (ns n' d) where n and n' are different n levels. 56. List the possible spectral terms 2S+1 L, resulting from the following two electron configurations in the same orbitals (n s), (np), (n d).
