We now understand crystal structure and how to measure it

We now understand crystal structure and how to measure it. We now move into bigger condensed matter questions. First up: What holds a crystal together? (A hot topic in early CMP) Generalization to nonzero temps (Helmholtz free en(V,T)) gives eq . thermodynamics

Shell model

Shell model. Notes: 1. The shell model is most useful when applied to closed-shell or near closed-shell nuclei. 2. Away from closed-shell nuclei collective models taking into account the rotation and vibration of the nucleus are more appropriate.
