Multipole response of doped ${}^3$He drops

Abstract

The multipole response of ${}^3$He${}_N$ drops doped with very attractive impurities, such as a Xe atom or an SF${}_6$ molecule, has been investigated in the framework of the Finite Range Density Functional Theory and the Random Phase Approximation. We show that volume ($L$ = 0) and surface ($L$ = 1, 2) modes become more fragmented, as compared with the results obtained for pure ${}^3$He${}_N$ drops. In addition, the dipole mean energy goes smoothly to zero when $N$ increases, indicating that for large $N$ values these impurities are delocalized in the bulk of the drop.
