A model of cosmic-ray (CR) production applied to the Galactic center to describe secondary-to-primary ratios and Galactic gradient data is extended to describe electron and positron fluxes. Parameters from the model by Said et al. (1981) modified by Wibig (1991) are fitted to experimental CR data to propose a modified CR propagation mechanism. Specific attention is given to the assumption that particles remain in the galactic halo for a long time. Assumptions are used to predict the proton spectrum and the primary electron spectrum, and the extra electron-positron component is assumed to be a power law to reconcile the two spectra. Observational data on the fraction of long-lived radioactive nuclei support the analytical predictions, and the results do not change if the CRs are produced around the Galactic center and not just in the center.
