Abstract
The localization of electrons in the field of isolated nonmagnetic impurity atoms on the surface of a nanotube is considered. A model of a Gaussian separable impurity potential capable of localizing an electron at any intensity is used. The positions of the local level are found. The positions of the resonances are found, their widths are estimated. It is shown that the positions of the resonances experience oscillations similar to the de Haas–van Alphen oscillations, when changing the radius of the tube.
