Abstract :
A comparative study of electrical conduction and emitted light in an atomic (Ar) and a molecular liquid (N2) is presented as a function of various parameters. From the spectroscopic analysis of emitted light (in the range 200 to 850 nm), the energy of the hot electrons in these liquids may be measured. A simultaneous study was carried out on dense gases as a function of the applied pressure. We discuss the electron swarm parameters deduced from these results, in an attempt to explain the behavior of electrons in the gas-liquid phase transition
