Title:

Dissociative Electron Capture by Halogenated Alkanes and Kinetics of the Low Energy Electron Attachment by Chloroalkanes

Date of publication:

Mar. 2005

Key words:

none

Abstract:

Data are presented for a series of halogen containing hydrocarbons closely related to the freon molecules studied by the use of electron capture negative ion mass spectrometry. Temperature dependence of negative ion effective yield is discussed. Thermal electron attachment processes in the mixtures of chloroalkanes with carbon dioxide have been investigated using an electron swarm method. All of them (except CH_2Cl_2) attach electrons only in a two-body process. Corresponding rate constants have been determined.
