Electron-Molecule Reactions The Thermalisation Problem

When studying an electron-molecule reaction one must consider two different temperatures the temperature of the gas (Tg) and the temperature of the electrons (Te), assuming they have a Maxwell-Boltzmann velocity 

There is stiU a great interest in developing the CRESU method for studies of electron attachment. This technique allows one to cool the neutral molecules down to very low temperatures in conditions of true thermodynamic equifibrimn. New developments are in progress to produce low energy electrons and avoid the buffer gas excitation using laser photoionisation of a precursor which has an ionisation potential close to the laser photon energy.
