Answer #1

The planck constant ( reduced ) is purely a quantum object. It measures the smallness of the quantum phenomena.
And the spin of each elementary particles is quantized in the unit of the planck constant .
   And so, if by angular momentum we mean the total angular momentum ( orbital + spin ), then the angular momentum is definitely quantized.
  Moreover, the dimension of the planck constant and the dimension of the angular momentum are equal. And so, we can say that the angular momentum should be quantized.

How is the total angular momentum vector J of a particle related to its linear momentum vector p? If p keeps the same magnitude but its direction is reversed, how can J stay constant? Maybe there is no relation between J and p and so J = L + S remains constant regardless of p? Please can you clarify?
