Abstract. The vibrationally and rotationally specific cross section is investigated for the dissociative recombination (DR) of H + 2 and HeH + using the multi-channel quantum defect theory. In order to give the zero energy cross section, a convolution formula is introduced. A systematics in the vibrational dependence of DR is made clear. The rotational motion plays an important role in the DR at energies lower than 0.1 eV, causing large enhancement in some cases and rotational sensitivity. The state-specific investigation indicates a possibility of a non-thermal distribution of the initial rotational states in storage-ring experiments on HD + .

Abstract.We have investigated the dissociative recombination (DR) of the C6D + 6 and C6D + 7 ions using the CRYRING heavy-ion storage ring at Stockholm University, Sweden. The dissociative recombination branching ratios were determined at minimal collision energy, showing that the DR of both ions was dominated by pathways keeping the carbon atoms together in one product. The absolute reaction cross sections for the titular ions are best fitted by σ (Ecm[eV] for C6D + 7 . These expressions correlates well with earlier flowing afterglow studies on the same process.

Aims. Determination of branching fractions, cross sections and thermal rate coefficients for the dissociative recombination of CD 3 OCD 2 + (0-0.3 eV) and (CD 3 ) 2 OD + (0-0.2 eV) at the low relative kinetic energies encountered in the interstellar medium. Methods. The measurements were carried out using merged electron and ion beams at the CRYRING storage ring, Stockholm, Sweden.Results. For (CD 3 ) 2 OD + we have experimentally determined the branching fraction for ejection of a single hydrogen atom in the DR process to be maximally 7% whereas 49% of the reactions involve the break up of the COC chain into two heavy fragments and 44% ruptures both C-O bonds. The DR of CD 3 OCD 2 + is dominated by fragmentation of the COC chain into two heavy fragments. The measured thermal rate constants and cross sections are k(T ) = 1.7 ± 0.5 × 10 −6 (T/300) −0.77±0.01 cm 3 s −1 , σ = 1.2 ± 0.4 × 10 −15 (E cm [eV]) −1.27±0.01 cm 2 and k(T ) = 1.7 ± 0.6 × 10 −6 (T/300) −0.70 ± 0.02 cm 3 s −1 , σ = 1.7 ± 0.6 × 10 −15 (E cm [eV]) −1.20±0.02 cm 2 for CD 3 OCD 2 + and (CD 3 ) 2 OD + , respectively.
