(a) Use Figure 11-35 to make a diagram like Figure 11-9 for the ground state of ¹¹B. What do you predict for the value of j for this state? 

(b) The first excited state of ¹¹B involves excitation of a proton. Draw the diagram for this state and predict its j value.

(c) The j value for the second excited state is 5/2. Draw a diagram of the nucleons like Figure 11-9 that could account for that value. 

(d) Repeat parts (a) and (b) for ¹⁷O, where the excitation of the first excited state involves a neutron.

(e) The j value for the second excited state of ¹⁷O is 1/2. Draw a diagram like Figure 11-9 that would explain that value.
