Hi;
In chapter 9 of Solid state physics of Ashcroft&Mermin(Electrons in a weak periodic potential),
there is a General Approch to the Schrodinger Equation when the Potential is Weak.
i can't understand what is meant by the term DEGENERACY?
or what does "nearly degenerate free electron levels mean"?
how should we visuallize degenerate and non-degenerate energy levels?
what are the differences and how can we interpret them?
i'm totally confused.
Thank u All.
