- lecture 14
- lecture 15
- lecture 16 (includes the handout on neutron scattering which you need for the homework)

- lecture 21 | handout on free electron gas heat capacity in 3D (for lectures 21 and 22). Note: in class on 25 Feb I caught a typo in the handout. Three are three places where the handout says "pi^3" where it should actually say "pi^2". The first place is in the final step of the density of states calculation. The other two places are (a) lower on the first page, and (b) near the top of the second page, where that D.O.S. calculation is used. Sorry about that!
