In order to check the electron thermalization in the CRESU technique (Cinétique de Réaction en Ecoulement Supersonique Uniforme, eg,“reaction kinetics in a uniform supersonic flow”), electron attachment on HI and DI has been studied in the 48–170 K range. Attachment to HI is exothermic and the reaction is expected to be fast and to proceed at a rate close to the capture limit. On the contrary, attachment to DI is slightly endothermic, ...
