There exist subatomic particles whose spin is characterized by s = 1, rather than the s = 1/2 of electrons. These particles are said to have a spin of one.

a. What is the magnitude (as a multiple of h) of the spin angular momentum S for a particle with a spin of one?

b. What are the possible values of the spin quantum number?

c. Draw a vector diagram similar to Figure 41.14 to show the possible orientations of S(vector).

For a spin-up state, S is somewhere on the surface of this cone. S, = +h. V3 >Length of S is h. For a spin-down state, Š is somewhere on the surface of this cone. S, = -h. /2
