Time independent Schrödinger Equation
... • The new wave functions are mixed in using the degree to which the overlap with the perturbation Hamiltonian is significant and by the closeness in energy of the states. • If some states are very close in energy, a perturbation generally results in a new state that is a linear combination of the or ...
