In this study, bounded real spectra of the Dirac equation have been found for a spherically symmetric completely imaginary linear potential in N dimensions. Negative-energy states lie on the regions m > E-n > -m, and E-n < -m, when the potential parameter A, k and the mass m satisfy certain constraints. (C) 1999 Elsevier Science B.V. All rights reserved.
