The effect of quantization of normal excitations in thin‐walled hollow superconducting cylinders on the critical temperature versus magnetic flux oscillations is considered. It is shown that the period of oscillations is he/e instead of hc/2e , as in the Parks‐Little effect. The phenomenon is connected with the so‐ called Aharonov‐Bohm effect and disappears if the quantum levels are smeared out, particularly dur to volume or surface scattering or finite temperature.
