Physical Review A. Vol. 65, 052708 (2002). ISSN 1050-29471050-29471094-1622 (electrónico)http://hdl.handle.net/10272/8132The coupling to the continuum is studied in a one-dimensional problem that describes the interaction of a weakly bound composite object with a wall in a semiclassical approach. A transformed harmonic oscillator basis is introduced to provide an appropriate discrete and finite basis for treating the continuum part of the spectrum. The convergence of the scattering magnitudes is investigated as the number of states in the basis is increased. The role of bound-to-continuum and continuum-to-continuum coupling is investigated.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Harmonic oscillatorOscilador armónicojournal article10.1103/PhysRevA.65.052708open access
