RT Journal Article T1 Spectroscopy of the Dirac oscillator perturbed by a surface delta potential A1 Munarriz, J. A1 Domínguez-Adame Acosta, Francisco A1 Lima, R. P. A. AB We study theoretically the level shift of the Dirac oscillator perturbed by any sharply peaked potential approaching a surface delta potential. A Green function method is used to obtain closed expressions for all partial waves and parities.
