The structure and energetics of 3He and 4He nanodroplets doped with alkaline earth atoms.

We present systematic results, based on density functional calculations, for the structure and energetics of He-3 and He-4 nanodroplets doped with alkaline earth atoms. We predict that alkaline earth atoms from Mg to Ba go to the center of He-3 drops, whereas Ca, Sr, and Ba reside in a deep dimple at the surface of He-4 drops, and Mg is a...更多
