We performed measurements on doped helium nanodroplets by the VUV- seeded FEL FERMI@Elettra. Using the FEL's high intensity and broad wavelength tunability, one can resonantly excite a large percentage of either the dopant or the cluster to look for effects of mutual interaction, such as the formation of nanoplasmas or energy transfer between dopant and cluster. In this regard, various dopants and their abundance along with cluster size were varied in order to fully exploit any possible observables.
