| 2 | Hyperfine structure |
| Hyperfine structure is a small perturbation in the energy levels (or spectral) of atoms due to the proton-electron dipole moment interaction. The amount of correction to the Bohr energy levels due to "hyperfine splitting" is on the order of: where m is the mass of an election, m p is the mass ... | |

| 15 | Level |
| In construction, level (as an adjective) is to horizontal what plumb is to vertical. A spirit level , or simply level , is a device used to measure and obtain a leveled surface, such as flooring or countertop, so that a ball will not roll around. In a building, a level is equivalent to a story or ... |
