Consider a system of two electrons, each with i 1 and s-h. (a) what are the possible values of the quantum number for the total orbital angular momentum l -li +l2? (b) what are the possible values of the quantum number s for the total spin s-s1 + s2? (c) using the results of parts (a) and (b), find the possible quantum numbers j for the combination j- l+s. (d) what are the possible quantum numbers j1 and j2 for the total angular momentum of each particle ul l1 + s1 and ½-l2 + ss). (e) use the results of part (d) to calculate the possible values of from the combinations of j1 and j2
