D 26, p. 350 (1993)**Abstract:**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`.
