11. OAM is distinct from, and should not be confused with, light spin angular momentum . 12. The intrinsic magnetic moment of a spin particle with charge, mass, and spin angular momentum , is 13. We can therefore think of the spin angular momentum of the photon being quantized as well as the energy. 14. The spin of the photon is defined as the coefficient of \ hbar in the spin angular momentum calculation. 15. This has been demonstrated for spin angular momentum , but it is in general true for any observable quantity. 16. In solutions of the Schr�dinger equation, angular momentum is quantized according to this number, so that total spin angular momentum 17. The 16 O nucleus has zero nuclear spin angular momentum , so that symmetry considerations demand that N may only have odd values. 18. The idea of a spin angular momentum was first proposed in a 1925 publication by Samuel Goudsmit to explain hyperfine splitting in atomic spectra. 19. Regarding the solar sail, the reflected light wouldn't transfer its spin angular momentum onto the sail, only the absorbed light. 20. Then once friction slows the energy of spin angular momentum the cue ball will continue in the original trajectory though on a slightly altered path.
