Spectroscopy of the Dirac oscillator perturbed by a surface delta potential Munarriz, J. Domínguez-Adame Acosta, Francisco Lima, R. P. A. ©2012 Elsevier B.V. All rights reserved. Work in Madrid was supported by MICINN (project MAT2010- 17180). R.P.A. Lima would like to thank CAPES via project PPCPMercosul, CNPq, and FINEP (Brazilian Research Agencies) as well as FAPEAL (Alagoas State Research Agency) for partial financial support. 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. 2023-06-20T03:54:45Z 2023-06-20T03:54:45Z 2012-08-15 journal article 0375-9601 10.1016/j.physleta.2012.10.029 https://hdl.handle.net/20.500.14352/44658 http://dx.doi.org/10.1016/j.physleta.2012.10.029 http://www.sciencedirect.com spa MAT2010-17180 PPCP-Mercosul open access Elsevier
