Resumen

FERNANDEZ-GARCIA, N. Darboux-deformed barriers and resonances in quantum mechanics. Rev. mex. fis. [online]. 2007, vol.53, suppl.4, pp.42-45. ISSN 0035-001X.

Scattering states in the continuum are used as Darboux transformation functions to deform square barrier potentials. The results include complex as well as real new potentials. It is shown that an appropriate superposition of Breit-Wigner distributions connects the transmission coefficient of one dimensional short range potentials.

Palabras llave : Darboux transformations; Gamow vectors; Breit-Wigner ditribution.
