The mutual neutralization of hydronium and hydroxide

A Bogot, M Poline, MC Ji, A Dochain, A Simonsson… - Science, 2024 - science.org
Mutual neutralization of hydronium (H3O+) and hydroxide (OH−) ions is a very fundamental
chemical reaction. Yet, there is only limited experimental evidence about the underlying …

Observation of an isotope effect in state-selective mutual neutralization of lithium with hydrogen

AF Schmidt-May, S Rosén, MC Ji, G Eklund… - Physical Review A, 2023 - APS
We report on mutual neutralization measurements between Li+ 7 and H− 1 at effective
center-of-mass collision energies in the range of 100 to 350 meV. We find that final states of …

State-Resolved Mutual Neutralization of and

J Grumer, G Eklund, AM Amarsi, PS Barklem… - Physical Review Letters, 2022 - APS
We present experimental final-state distributions for Mg atoms formed in Mg++ D-mutual
neutralization reactions at center-of-mass collision energies of 59±12 meV by using the …

Isotope effect for the mutual neutralization reaction at low collision energies:

A Dochain, VM Andrianarijaona, X Urbain - Physical Review A, 2023 - APS
We measured the branching ratios of the He++ H− and He++ D− mutual neutralization at a
collision energy below 25 meV. Those are correctly reproduced using the Landau-Zener …

Mutual neutralisation of O+ with O−: investigation of the role of metastable ions in a combined experimental and theoretical study

M Poline, A Dochain, S Rosén, J Grumer… - Physical Chemistry …, 2021 - pubs.rsc.org
The mutual neutralisation of O+ with O− has been studied in a double ion-beam storage ring
with combined merged-beams, imaging and timing techniques. Branching ratios were …

Storage-ring study of the mutual neutralization of with

M Poline, S Rosén, MC Ji, A Simonsson, P Reinhed… - Physical Review A, 2022 - APS
The double ion storage ring DESIREE has been used in combination with position-and time-
sensitive detectors to study the mutual neutralization of N+ with O− at 40 meV collision …

Final-state-resolved mutual neutralization in - collisions

M Poline, X Yuan, S Badin, M Ji, S Rosén, S Indrajith… - Physical Review A, 2022 - APS
We have studied the mutual neutralization reaction of atomic iodine ions (ie, I++ I−→ I+ I) in
a cryogenic double electrostatic ion-beam storage-ring apparatus. Our results show that the …

Mutual neutralization in collisions: An improved theoretical model

J Hörnquist, P Hedvall, Å Larson, AE Orel - Physical Review A, 2022 - APS
The total and differential cross sections of mutual neutralization in H++ H− collisions are
calculated ab initio and fully quantum mechanically for energies between 0.001 and 600 eV …
