Resumen

We find quantum states that are spatially localized by two potential barriers due to commensurability between the total length of the system and the distance between the barriers. Such states are resonant because they coexist with nearly continuum states, as found in the present one-dimensional Schrödinger equation investigation. They exist even in the case of weak and thin barriers, and we discuss them here in the context of conducting films made by bismuth whose mean free path is abnormally large.
