Rocco Física, Astronomía y Matemáticas Synchrotron radiation Condensed carbon dioxide Photon stimulated ion desorption (PSID) ray induced Electron Stimulated Desorption (XESD) Photon stimulated ion desorption (PSID) from condensed carbon dioxide has been studied for photon excitationenergies ranging from 93 to 193 eV. PSID studies have been performed at the Brazilian synchrotron lightsource (LNLS), Campinas, during a multi-bunch operation mode of the storage ring. The results showed thatafter photon excitation several ions desorbed from the CO2 films: C+, O+, CO+ and O+2 . PSID experimentsshowed that ion desorption was enhanced only at the Si resonance excitations. When the thickness of the CO2was » 500 L or higher, almost no desorption yield was observed. The study of the dependence of the relativepartial ion yield on the photon excitation showed that the X-ray induced Electron Stimulated Desorption(XESD) mechanism has to be invoked to explain the origin of the desorbed ions in the energy region studied 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436547 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3B Vol.36 |
