摘要：

We have investigated how helium atoms are distributed within a mixed (HeN3)-He-3-(HeN4)-He-4 large drop with N-3 >> N-4. For drops doped with a SF6 molecule or a Xe atom, we have found that the number of He-3 atoms within the volume containing the first two solvation shells increases when N-4 decreases in such a way that these dopants may be in a superfluid environment for N-4 greater than or equal to 60, which gradually disappears as N-4 decreases. The result is in qualitative agreement with recent experimental data. [S0031-9007(99)08864-X].
