Formation of the simplest stable negative molecular ion H3- in interstellar medium (2009)
Kokoouline, V., Ayouz, M., Guerout, R., Raoult, M., Robert, J., Dulieu, O.
We present the theory of radiative association of atoms and molecules, and we apply it to the (H$_2$-H$^-$) van der Waals complex. We discuss the possibility for the H$_3^-$ ion to be formed in the...
Temperature dependence of binary and ternary recombination of H3+ ions with electron (2009)
Glosik, J., Plasil, R., Korolov, I., Kotrik, T., Novotny, O., Hlavenka, P., ...
We study binary and the recently discovered process of ternary He-assisted recombination of H3+ ions with electrons in a low temperature afterglow plasma. The experiments are carried out over a broad...
Chemical modeling of L183 (L134N): an estimate of the ortho/para H_2 ratio (2009)
Pagani, L., Vastel, C., Hugo, E., Kokoouline, V., Greene, C. H., Bacmann, A., ...
The high degree of deuteration observed in some prestellar cores depends on the ortho-to-para H_2 ratio through the H_3^+ fractionation. Aims. We want to constrain the ortho/para H_2 ratio across the...
Recombination of H3+ Ions in the Afterglow of a He-Ar-H2 Plasma (2007)
Glosik, J., Korolov, I., Plasil, R., Novotny, O., Kotrik, T., Hlavenka, P., ...
Recombination of H3+ with electrons was studied in a low temperature plasma in helium. The plasma recombination rate is driven by two body, H3+ + e, and three-body, H3+ + e + He, processes with the...
Near-threshold rotational excitation of molecular ions by electron impact (2006)
Faure, A., Kokoouline, V., Greene, C.H., Tennyson, J.
New cross sections for the rotational excitation of H+3 by electrons are calculated ab initio at low impact energies. The validity of the adiabatic-nuclei-rotation (ANR) approximation, combined with...
Near threshold rotational excitation of molecular ions by electron-impact (2006)
Faure, A., Kokoouline, V., Greene, Chris H., Tennyson, Jonathan
New cross sections for the rotational excitation of H$_3^+$ by electrons are calculated {\it ab initio} at low impact energies. The validity of the adiabatic-nuclei-rotation (ANR) approximation,...
Tuning the scattering length on the ground triplet state of Cs_2 (2000)
Kokoouline, V., Vala, J., Kosloff, R.
We develop two schemes for tuning the scattering length on the ground triplet state of Cs_2. First, an absolute value of the triplet scattering length of ^{133}Cs_2 is determined using the...
