Although the potential determined the space-dependent wavefunction, there was no limitation imposed on the possible wavenumbers and energies involved.

lejpt.academicdirect.orgquantized. Quantization of energy of the particle is a remarkable feature of the quantum mechanics i.e. a particle cannot have any energy or continuous energy, but can have only that permitted energy described by Schrödinger equation together with the potential V and the boundary conditions [10, 11].
