Summary
Calculated 4f1<a href="https://en.wikipedia.org/wiki/Atomic_orbital" class="extiw" title="en:Atomic orbital">orbital</a> of an electron's eigenstate in the Coulomb-field of a hydrogen nucleus. An <a href="https://en.wikipedia.org/wiki/Eigenfunction" class="extiw" title="en:Eigenfunction">eigenstate</a> is a state which keeps it's shape except for a complex phase when the <a href="https://en.wikipedia.org/wiki/Hamiltonian_(quantum_mechanics)" class="extiw" title="en:Hamiltonian (quantum mechanics)">Hamilton operator</a> is applied, thus being invariant in time while obeying the <a href="https://en.wikipedia.org/wiki/Schr%C3%B6dinger_equation" class="extiw" title="en:Schrödinger equation">Schrödinger equation</a>. The orbital is aligned around the z-axis, but remains an eigenfunction if rotated to any direction.
