| dc.description | Ion yield spectra and angular distributions of Cl<sup>-</sup> and I<sup>-</sup> ions formed by dissociative electron attachment on ICl molecules have been obtained with a crossed-beam electron impact spectrometer, in the 0-6 eV energy range. Kinetic energy and angular measurements show that two ICl<sup>-</sup> states with <sup>2</sup> Pi <sub>3/2</sub> and <sup>2</sup> Pi <sub>1/2</sub> symmetry are involved in Cl<sup>-</sup> ion formation, one around 0.85 eV, associated with <sup>2</sup>P<sub>3/2</sub> neutral fragments, and the other around 4.55 eV (+I <sup>2</sup>P<sub>1/2</sub>) respectively, whereas a <sup>2</sup> Sigma <sup>+</sup> and a <sup>2</sup> Pi resonance state are responsible for the I<sup>-</sup> (+Cl<sup>2</sup>P) ion formation around 1.45 and 3.7 eV respectively. The Cl<sup>-</sup> and I<sup>-</sup> relative differential cross sections do not show evidence of non-adiabatic dissociation processes. The analysis of the measured angular distributions also does not show any effect of the spin-orbit interaction upon the symmetry of the resonances, since they are found to have a pure Lambda -type symmetry. |
