The conductance resulting from resonant tunneling through a droplet of N ∼ 30 electrons is used to measure its chemical potential μN. Abrupt shifts of μN occur at sharply defined values of the magnetic field, at which the state of the droplet changes. These are used to study part of the phase-diagram of the droplet in strong magnetic fields; we find evidence for a new phase in the spin polarized regime. We make a detailed comparison between theory and experiment: Hartree-Fock provides a quantitative description of the measurements when both spin-split states of the lowest orbital Landau level are occupied and a qualitative one in the spin polarized regime.
