We have investigated how helium atoms are distributed within a mixed 3HeN3-4HeN4 large drop with N3≫N4. For drops doped with a SF6 molecule or a Xe atom, we have found that the number of 3He atoms within the volume containing the first two solvation shells increases when N4 decreases in a way such that these dopants may be in a superfluid environment for N4≥ 60, which gradually disappears as N4 decreases. The result is in qualitative agreement with recent experimental data.
