Description
| - Rekombinace spektroskopicky identifikovaného iontu H3+ (v=0) s termálními elektrony byla studována v pulsní afterglow plasmě s použitím infračerveného cavity-ringdown spektrometru (CRDS). Časově rozlišená měření byla prováděna v plynném heliu s přídavky malého množství argonu a vodíku. Teplota plynu byla ~ 330K, a celkový tlak byl v rozmezí od 8 do 16 mbar. Signál CRDS na přechodu .nu.2=3<--0 iontu H3+ (.lambda. = 1.4um) byl monitorován v závislosti na čase v průběhu afterglow fáze výboje. Jelikož absorpční průřez je známý, úbytek koncetrace částic a tedy rekombinační koeficient může být určen. Pro koncetraci vodíku v rozmezí 1x1014 až 8x1014 cm-3 má změřený rekombinační koeficient hodnotu .alpha.=(1.6+/-0.6)x10-7cm3s-1. (cs)
- The recombination of spectroscopically identified H-3(+)(upsilon = 0) ions with thermal electrons has been studied in pulsed afterglow plasma by means of an infrared cavity ring-down spectrometer (CRDS). Time-resolved measurements of the H-3(+)(upsilon = 0) density were carried out in helium buffer gas with small admixtures of argon and hydrogen. The gas temperature was similar to330K, and the total pressure ranged from 8 to 16 mbar. The CRDS signal on the upsilon(2) = 3 <-- 0 transition of H-3(+) (lambda = 1.4 mum) was monitored as a function of time during the discharge aftergalow. Since the absorption cross-section is known, the decay of the H-3(+)(upsilon = 0) number density and hence, the recombination coefficient can be deduced. At hydrogen number densities [H-2] = 1 x 10(14) to 8 x 10(14) cm(-3) the measured recombination rate coefficient was found to be alpha = (1.6 +/- 0.6) x 10(-7) cm(3) s(-1).
