A. %T Spectroscopy of the Dirac oscillator perturbed by a surface delta potential %D 2012 %@ 0375-9601 %U https://hdl.handle.net/20.500.14352/44658 %X 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. %~
