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 ℏ) 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 41.13 to show the possible orientations of S.
