SUMMARY
The discussion focuses on the tight binding model as illustrated in Figure 10.6 on page 184 of "Solid State Physics" by Ashcroft and Mermin. It clarifies that the line along the gamma point (Γ) is not doubly degenerate, while the line along the L point is doubly degenerate due to the energy values of d orbitals. The diagram indicates that there should be five lines representing the d orbital states, but only three and four are shown in the first two diagrams due to degeneracy effects, which result from overlapping solutions.
