State-resolved mutual neutralization of
O+16
with
We measured the product-state distribution and its dependence on the hydrogen isotope for the mutual neutralization between O+16 and H−1,2 at the double electrostatic ion-beam storage ring DESIREE for center-of-mass collision energies below 100 meV. We find at least six product channels into ground-state hydrogen and oxygen in different excited states. The majority of oxygen products populate terms corresponding to 2s22p3(4S∘)4s with S∘5 as the main reaction product. We also observe product channels into terms corresponding to 2s22p3(4S)3p. Collisions with the heavier hydrogen isotope yield a branching into these lower excited states smaller than collisions with H−1. The observed reaction products agree with the theoretical predictions. The detailed branching fractions, however, differ between the theoretical results, and none of them fully agree with the experiment.

期刊介绍：
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
