Calculation of Exact Eigenfunctions of Spin and Angular Momentum Using the Projection Operator Method

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Sfl. Introducing the identity sfz =622.i; and making use of the fact that j is now an eigenfunction having M L we can replace diz by L and rewrite Eq. (3) in the form.
