STRUCTURE AND STABILITY OF HE-3 DROPLETS

We have studied the structure of He-3 droplets at zero temperature usi ng a density functional approach plus a configuration interaction calc ulation in an harmonic oscillator major shell. The most salient featur e of open shell drops is that the valence atoms couple their spins to the maximum value compatible with Pauli's principle, building a large magnetic moment. We have determined that 29 atoms constitute the small est self-hound droplet.
