Excitation of the 4.3-μm bands ofCO2by low-energy electrons

Dissociation of molecules in plasma and gas: the energy

“…Second, the mentioned assumption requires for that initially all input energy be con tributed to one dergee of freedom. Direct experiments [32]show that under optimum conditions ( electron meaA energy -1…”

Temperature Dependence of the Diffusion Coefficient for Thermal Electrons in Carbon Dioxide over the Range 296 - 468 K

“…f-lNth, decreases with increasing temperature T. This variation is in the opposite sense to that predicted when the momentum transfer cross section O'm of Bulos and Phelps (1976) is used to calculate the mobility, using the relation…”

Modelling of an IR scintillation counter

“…The de-excitation of the N (v"1) level includes the energy transfer to the CO (0,03,1) level and collisional de-activation by nitrogen molecules on their ground states [12]. The upper vibrational states of N also de-excite either by an energy transfer mechanism to the corresponding resonant CO (0,03,n) levels or by two-body collisions to a lower vibrational state [14].…”

“…This clearly depends on the geometry of the chamber. To give an idea of the e!ect of reabsorption of these photons by CO we take the results of Bulos and Phelps [12], who calculated the transmission factor for CO /N mixtures. According to their results the transmission factor depends on the Table 1 Transmission factor for two CO concentrations and two absorption lengths relative concentration of CO and on the distance between the point of production and the window.…”

“…The kinetic scheme for the de-excitation of the CO (0,03,1) level includes its radiative decay, the energy transfer process to the N (v"1) vibrational state and its de-excitation by two body collisions with species (Ar atoms, CO and N molecules) on their ground states [12,13]. The de-excitation of the N (v"1) level includes the energy transfer to the CO (0,03,1) level and collisional de-activation by nitrogen molecules on their ground states [12].…”
