✦ Synopsis

Variational calculations of the ground state structure and the excitation spectrum of 4He clusters doped with an SFs molecule show that, for clusters size larger than approximately 100 atoms, a spherically symmetric configuration with the impurity molecule at the center of the cluster is unstable. The instability is indicated by the 'softening' of the droplet's collective dipole excitation. This instability strongly suggests that the SF, molecule is delocalized inside larger helium droplets and may be found near a non-isotropic environment such as the surface.

The gas-phase clustering reactions of SF~, SF 6 and F-ions with SF 6 were measured using a high-pressure mass spectrometer. The bond energies of SFs--(SF6) 1 and SF6(SF6) 1 were estimated to be ~< 2.3 kcal/mol. The bond energies of F-(SF6) , with n = 1 and 2 were determined to be 5.4 and = 4.1 kcal/
