“…We can see a rapid decrease of the gas temperature and N 2 , O 2 molar fractions close to the shock front due to dissociation and forward reactions (37), (38) and rising of number densities of atoms and NO molecules for M 0 ¼ 15. Then accumulation of free atoms calls intensive reverse reaction (37) as well as reaction (38), which lead to non-monotonous n NO =n changing for M 0 ¼ 15. The low nitrogen atom concentration is explained by more intensive reaction (37) of lower temperature values just behind the shock front.…”

“…17 and 18. It reflects the character of the state-dependent rate coefficients for reactions (37) and (38) discussed in the Section 3. We can notice very close populations of low lying levels in the thin region close to the shock front, the difference becomes noticeable for higher levels.…”

“…Quasi-classical trajectory calculations for vibrational energy transitions and dissociation in (N 2 , N) and (O 2 , O) systems are carried out in [43][44][45]. Analytical expressions are proposed by Capitelli et al [26,37] for interpolation of accurate trajectory calculations of Billing et al [38,39] for vibrational energy transitions in (N 2 , N) and (O 2 , O) mixtures. These approximations are convenient for a practical use but they are given for temperatures lower than 12,000 K and not for all collisions in the considered five-component air mixture.…”

“…To study the influence of different models for exchange reactions on gas flow parameters and vibrational distributions in the relaxation zone we compare the results obtained with the use of four models for the rate coefficients of reactions (37) and (38) given in the Section 3. considered models is shown in Figs. 17 and 18.…”

For a typical laser gas discharge, the concentration and temperature of the most important plasma components a t the end of the current pulse are calculqted on the basis of given data for the tube radius, gas pressure, andenergy input. Relating to a postdischarge time up to 1 s, the deionization, the association of the nitrogen atoms, the deexcitation of metastable molecules and the relaxation of the vibration temperature are investigated by means of simple balance equations. F.inaIly the influence of plasma relicts on the following discharge pulse is discussed. InhaltsiibersichtBus vorgegebenen Werten fur Rohrradius, Druck und investierter Energie werden fur eine typische Impulslaser-Gasentladung in Stickstoff die Konzentrationen und Temperaturen der wesentlichen Plasmakomponenten berechnet, die unmittelbar nach Beendigung des Stromimpulses vorliegen., AnschlieBend wvetden fur Zeiten bis zu 1 s die Deionisation, die Assoziation der Stickstoffatome, die Abregung metastabiler Molekule und die Relaxation der Schwingungstemperatur rechnerisch verfolgt. AbschlieBend wird der EinfluR verschiedener Plasmarelikte auf den nachfolgenden Entladungsimpuls diskutiert.
