Angular momentum
... Let us assume that the operators (Lx , Ly , Lz ) ≡ L which represent the components of orbital angular momentum in quantum mechanics can be defined in an analogous manner to the corresponding components of classical angular momentum. In other words, we are going to assume that the above equations sp ...
