Título: | Study of the diffraction mediated selective adsorption through the close-coupling and diabatic distorted wave formalisms. Application to the 4He-Cu(110) system |
Autor: | Hernández, Marta I. CSIC ORCID; Roncero, Octavio CSIC ORCID ; Miret-Artés, Salvador CSIC ORCID; Villarreal, Pablo CSIC ORCID; Delgado Barrio, Gerardo CSIC ORCID | Fecha de publicación: | 1989 | Editor: | American Institute of Physics | Citación: | Journal of Chemical Physics 90: 3823- 3830 (1989) | Resumen: | Two different formalisms, one based on close-coupling equations and other on the distorted wave approximation, have been applied to the low energy elastic scattering of 4He atoms by a corrugated copper surface, Cu(110). Diffraction intensities and energetic positions and half-widths (selective adsorption resonances) have been obtained and compared with experimental and previous theoretical results, respectively. For this trapping process, and within the close-coupling framework, a plot of the diffraction channels (open and closed) has turned out to be very useful and a good guide in order to know the disposition of them at each interesting angular region. Also, a very accurate method, already employed successfully to treat resonances in the vibrational and/or rotational predissociation of van der Waals molecules, has been found to be also adequate here. © 1989 American Institute of Physics. | URI: | http://hdl.handle.net/10261/72440 | DOI: | 10.1063/1.455839 | Identificadores: | doi: 10.1063/1.455839 issn: 0021-9606 |
