Animated Physics - Quantum Spin

1. Quantum Spin States, Spin 1/2 - two states of +1/2 (up) and -1/2 (down)
(a) Nucleons tilted & separated for viewing(b) Neutron and Proton spin 1/2 - up/down flips(c) Helium-3 spin 1/2 - up/down flips
2. Spin 1 - three states of +1 (2 up), 0 (1 up and 1 down) and -1 (2 down)
(a) Hydrogen-2 spin 1 - three states(b) Lithium-6 spin 1 - three states(c) Proton pair coupled - no state change
3. Other Spin States - Spin 0 with one state, Spin 3/2 with four spin states = +3/2, +1/2, -1/2 and -3/2
(a) Helium-4 spin 0 - one state(b) Lithium-7 spin 3/2 - four states(c) Proton/Neutron couples - no state change
