Abstract

SynopsisDoped He droplets constitute an important environment as ultracold homogeneous matrices for spectroscopic studies. Alkali metal dopants have a series of interesting properties due to their unusual bonding behavior. Neutral atoms attached to the surface of the droplet, forming eventually cold molecules via collisions, while charged dopants form solvation shells, related with the low mobility of the ions in experiments. So, investigations on the underlying intermolecular, markedly orientational ionic, forces, and on the miscoscopic structures of alkali-cation-He complexes is essential.

Highlights

  • Synopsis Doped He droplets constitute an important environment as ultracold homogeneous matrices for spectroscopic studies

  • The structural characteristics and stabilities of such cations are determined from high level ab initio electronic structure calculations

  • Interaction energies are obtained from CCSD(T)/CBS and MRCI+Q calculations, depending on the single- or multi-reference character of the system under study
