WebRegarding symmetry: The wavefunctions do not need to have the same symmetry as the potential. Of course if you have a solution wavefunction, then the mirrored wavefunction must be a solution as well (if the potential is symmetric as in your case). It needs to belong to the same energy eigenvalue. WebMay 4, 2024 · Anyway, quantum mechanics (that is, Schroedinger's Equation) shows that a particle can exist in a region where his energy is lower than the potential energy governing the region (although the wave-function is exponentially decaying), and it even can penetrate a finite potential step, which is known as the Tunnel Effect.
