Theoretically and numerically, the presence of a system of short-lived volume-localized electronic states in positively charged nanotubes is shown by the example of a single-wall carbon nanotube (5,5). Unlike electron states that are well studied theoretically and experimentally, localized in a thin surface layer, these electron states are due to the flat part of the Coulomb potential of a positively charged nanotube cylinder. The maximum electron density of such states is located along the axis of the nanotube. The energy width of the system of such discrete body-localized levels depends on the charge and increases with its increase. The published papers show theoretically and experimentally the existence of metastable positively charged nanotubes with a charge of +10 e per 120 atoms or more, which suggests the possibility of experimental observation of the system of volume-localized electronic states under consideration..
