Stationary afterglow with Cavity Ring Down Spectrometer was utilized to probe the number densities of H3+, H2D+, HD2+ and D3+ ions in discharge and afterglow plasma. The recombination rate coefficients for recombination of H2D+ and HD2+ ions with electrons were obtained from the time decays of overall ion number density at different fractions of [H2]/[D2].

Dissociative recombination of N2H+ ions with electrons in the temperature range of 80-350 K.

The newly calculated vibrational transition moments of N2H+ are used to explain the different values of recombination rate coefficients obtained in some of the previous studies.

Compared with earlier years, the dissociative recombination of H3+ has not been very actively studied in recent years. New results from afterglow experiments are quoted and compared with results from

Stationary afterglow measurements of the temperature dependence of the electron–ion recombination rate coefficients of H 2 D + and HD 2 + in He/Ar/H2/D2 gas mixtures at T = 80–145 K

We report measurements of the binary and ternary recombination rate coefficients of deuterated isotopologues of H 3 + . A cavity ring-down absorption spectrometer was used to monitor the fractional

Electron-ion recombination in low temperature hydrogen/deuterium plasma

The stationary afterglow with cavity ring down spectrometer (SA-CRDS) was used to study the recombination of H3 +, H2 D+ , HD2 + and D3 + ions with electrons in low temperature plasmas in He/Ar/H2 /D2 gas mixtures and observed very efficient He assisted ternary recombination.



Recombination of H+3 ions in the afterglow of a He–Ar–H2 plasma

It is suggested that the ternary recombination involves formation of neutral highly excited Rydberg H3 followed by an l-changing collision with He in a low-temperature plasma containing He, H2 and Ar.

Ternary recombination of H3(+) and D3(+) with electrons in He-H2 (D2) plasmas at temperatures from 50 to 300 k.

Results of plasma afterglow experiments on ternary electron-ion recombination rate coefficients of H3 (+) and D3(+) ions at temperatures from 50 to 300 K are presented and a semiquantitative model is proposed that reconciles several previously discrepant experimental observations.

Recombination of H+3 ions with electrons in He/H2 ambient gas at temperatures from 240 K to 340 K

We have studied the recombination of H3+ ?> ions with electrons in a stationary afterglow experiment either in pure hydrogen or in mixtures of helium, hydrogen, and argon. The decay of the ion

Binary recombination of H3(+) and D3(+) ions with electrons in plasma at 50-230 K.

This is the first measurement of the binary recombination rate coefficient of H3 (+) and D3(+) ions in a plasma experiment down to 50 K.

High-resolution dissociative recombination of cold H3+and first evidence for nuclear spin effects.

The energy-resolved rate coefficient for the dissociative recombination (DR) of H(3)(+) with slow electrons has been measured by the storage-ring method using an ion beam produced from a

Evidence for subthermal rotational populations in stored molecular ions through state-dependent dissociative recombination.

We demonstrate that the dissociative recombination of D2H+ with low-energy electrons depends on the rotational energy of the molecular ion such that highly excited ions have a larger rate coefficient

The recombination of D+3 and D+5 ions with electrons in deuterium containing plasma

If the ion–molecule reactions are fast in comparison with the recombination processes the plasma decay can be characterized by the equilibrium constant KC and by recombination rate coefficients α3 and α5.

Binary and ternary recombination of para-H3(+) and ortho-H3(+) with electrons: state selective study at 77-200 K.

The results show that H(3)(+) recombination with electrons occurs by both binary recombination and third-body (helium) assisted recombination, and that both the two-body and three-body rate coefficients depend on the nuclear spin states.

Nuclear spin effect on recombination of H₃⁺ ions with electrons at 77 K.

Using different ratios of para to ortho H₂ in normal and para enriched hydrogen, the rate coefficients for binary recombination of para-H₃⁺ and ortho-H³⁺ ions were determined and the densities of the two lowest rotational states of H‽⁺ were measured.
