Abstract

Inelastic excitation and charge transfer excitation processes in collisions between neutral Mg atoms and Cs+ ions, both in their ground states, have been studied by means of a crossed molecular beam technique. Decay fluorescent emissions from Mg(3 1P1), Mg(3 3D3,2,1), Mg(4 3S1) and Cs(6 2P3/2) states have been detected as well as the phosphorescent emission due to Mg(3 3P1) decay. The corresponding absolute cross-sections vs. collision energy functions were determined in the laboratory 0.05–4.20 keV energy range. In order to interpret the experimental results, accurate ab initio calculations using pseudopotentials have been performed for the (Mg–Cs)+ system obtaining a manifold of adiabatic energy curves correlating with the different collision channels and allowing a qualitative interpretation of the emission excitation functions for the different processes studied.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
