Quantum Mechanics: Hydrogen Atom
0.0 out of 5 stars
Teaching Materials | 09 Jul 2008 | Contributor(s): Dragica Vasileska, Gerhard Klimeck
The solution of the Schrödinger equation (wave equations) for the hydrogen atom uses the fact that the Coulomb potential produced by the nucleus is isotropic (it is radially symmetric in space and only depends on the distance to the nucleus). Although the resulting energy eigenfunctions (the...
