Binary and ternary recombination of para-H-3(+) and ortho-H-3(+) with electrons: State selective study at 77-200 K
Original language description
Measurements in H-3(+) afterglow plasmas with spectroscopically determined relative abundances of H-3(+) ions in the para-nuclear and ortho-nuclear spin states provide clear evidence that at low temperatures (77-200 K) para-H-3(+) ions recombine significantly faster with electrons than ions in the ortho state, in agreement with a recent theoretical prediction. The cavity ring-down absorption spectroscopy used here provides an in situ determination of the para/ortho abundance ratio and yields additionalinformation on the translational and rotational temperatures of the recombining ions. 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-bodyand three-body rate coefficients depend on the nuclear spin states. Electron-stabilized (collisional-radiative) recombination appears to make only a small contribution. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1
