Problem 1 Determine all the possible values of the integral j,mjj^2j,mj for a single pz-electron. Problem 2 Consider an electron in the 4d state of hydrogen. a) In the absence of spin-orbit coupling, give the quantum numbers l and s and the total number of states in which this electron can reside. b) Now consider spin-orbit coupling. What are the quantum numbers j ? How many states are there
