A heavy particle impact vibrational excitation and dissociation model for CO2 is presented. This state-to-state based on the forced harmonic oscillator (FHO) theory, which more accurate than current state-of-the-art kinetic models of first-order perturbation theory. The first excited triplet state 3B2 CO2, including its structure, considered in our model, a consistent approach to also proposed....

One of the unresolved questions related to the mechanism of action of light negative air ions (reactive oxygen species) produced by air ionizers upon humans and animals is transmission of these short-living chemical species upon long distances from the place of their origin. We discovered the phenomenon which may probably resolve this problem. When a thin layer of water hydrating a hygroscopic ...

In this paper I should like to review briefly the present status of the chemistry of visual excitation, specifically in vertebrates; and then to discuss connections between these processes and visual physiology and pa­ thology. Light initiates a nervous excitation in the outer segments of the rods and cones which, transmitted from one neurone to another to centers in the brain, ends in exciting...

The enhancement of excitation and reemission of molecules in close proximity to plasmonic nanostructures is studied with special focus on the comparison between idealized and realistically shaped nanostructures. Numerical experiments show that for certain applications choosing a realistic geometry closely resembling the actual nanostructure is imperative, an idealized simulation geometry yieldi...

The isotope effect and excitation-energy dependence have been measured in the oxygen K-edge x-ray emission spectrum (XES). The use of XES to monitor core decay processes provides information about molecular dynamics (MD) on an ultrafast time scale through the O1s lifetime of a few femtoseconds. Different nuclear masses give rise to differences in the dynamics and the observed isotope effect in ...

An extensive cross section database for the electron-impact inelastic processes of vibrationally excited molecules of hydrogen and its isotopes is presented. The following inelastic processes are covered: electronic excitation (dissociative and nondissociative), direct ionization (dissociative and nondissociative), excitationradiative decay vibrational excitation and dissociation, and dissociat...

We derive simple and physically transparent expressions for the contribution of the strong interaction to one nucleon removal processes in peripheral relativistic heavy ion collisions. The coherent contribution,i.e, the excitation of a giant dipole resonance via meson exchange is shown to be negligible as well as interference between coulomb and nuclear excitation. Incoherent nucleon knock out ...

We discuss the use of uncorrelated final state wave functions in calculations of double ionization processes. We show that in some physical situations such a simplified treatment can provide meaningful results. In particular, the prevalence of back-to-back emission in two-photon double ionization and even energy sharing between the photoelectrons make it possible to use uncorrelated final state...
