The excited short-lived volume-localized electron quantum levels (VLELs) existent due to Coulomb potential well inside positive ion C₆₀^+z  are analytically investigated in the paper using a simplified spherical fullerene model. Hence, those electron levels appear exclusively after the ionization of neutral fullerene taking into account the unique geometrical shape of sphere. The existence of those levels is argued, and their basic parameters (the energy levels, the wave eigenfunctions) are approximately calculated. The analysis of electron beam interaction with the medium consistent of fullerenes ions C₆₀^+zis conducted as the application of the methods developed. The analytical dependencies of free electron recombination cross-sections for the capture to the volume-localized electron levels are obtained. It is shown that the probabilities of electron capture to these VLELs are considerably larger compared to capture to SLELs.  Also, the calculational results of dipole moments for quantum transitions from fullerene ions VLELs to other VLELs and to SLELs with spontaneous photon emission are also presented in the paper. Finally, the principal possibility of coherent radiation generation on fullerene ions’ VLELs is discussed.
