] gives the x component of the total angular momentum operator for angular momentum Details and Options
- GTJx gives a matrix representation of the x component of the total angular momentum operator acting on an irreducible subspace with quantum number J.
- Jx is related to the raising operator J+ and lowering operator J- by Jx=(J++J-)/2 i (see GTJplus, GTJminus)
- GTJx is a GTPack command [1,2].
