摘要

Experimental and theoretical results for mixed helium droplets doped with one calcium atom are reported. The absorption spectrum around the 4s4p←4s~2 transition is calculated as a function of the composition of the droplet and compared to the experiment. Our study reveals the distinct feature that for specific " He concentrations, Ca atoms sit at the ~3He-~4He interface. This particular property of Ca, likely not shared with any other atomic or molecular species but the heavier alkaline-earth atoms, might offer the possibility of using it to probe the ~3He-~4He interface of the droplet.
