    "abstract": "Variational MonteCarlo and Diffusion MonteCarlo calculations have been\ncarried out for cations like Li$^+$, Na$^+$ and K$^+$ as dopants of small\nhelium clusters over a range of cluster sizes up to about 12 solvent atoms. The\ninteraction has been modelled through a sum-of-potential picture that\ndisregards higher order effects beyond atom-atom and atom-ion contributions.\nThe latter were obtained from highly correlated ab-initio calculations over a\nbroad range of interatomic distances.\n  This study focuses on two of the most striking features of the microsolvation\nin a quantum solvent of a cationic dopant: electrostriction and snowball\neffects. They are here discussed in detail and in relation with the nanoscopic\nproperties of the interaction forces at play within a fully quantum picture of\nthe clusters features.",
