... 1. Units for length and energy A convenient unit of length for description of solids is the nanometer (nm), which is the order of magnitude of a typical distance between atoms. (Actual sizes are between 0.1 nm and 1.0 nm. Many older texts use the Angstrom = 0.1 nm.) A convenient unit of energy is t ...

... needed because the electron spin can be +1/2 or -1/2). Still, to specify the particle state completely we need all four quantum numbers (n, l, m, ms ). Indeed, when higher-order effects are considered, or perturbations from external fields such as magnetic fields, the degeneracy in energy is broken. ...
