Using the Path Integral Monte Carlo method we calculate the structural and
energetic properties of small spin polarized Li+ 3He_N (1<=N<=7) clusters. To
investigate the Pauli principle effects we perform  calculations using Fermi
Dirac statistics as well as  Boltzmann statistics. It turns out that FD
statistics affects mainly the structure of the very small clusters. Energetic
effects are significant but very small. We found a dominant magic number at
N=6. For the spatial pair correlations we find an interesting counterplay of
FD statistics induced spatial hindrance due to shell occupation and  the known
short range `repulsion`.
