Abstract = {We have fabricated few electron lateral dots containing between 10 and 20 electrons. Single electron spectroscopic techniques have been used to investigate the regime between v = 2 and v = 1, i.e., the transition from a spin unpolarized quantum dot to a spin polarized quantum dot. We compare the experimental results to non-interacting, Hartree-Fock and exact diagonalization calculations. The comparison confirms that correlations are important in this regime. Spinflips are found to be complex and rich phenomena involving a nontrivial spin polarization dependence on magnetic field and a resulting collapse of the Zeeman gap due to electronic correlations. {\copyright} 1998 Elsevier Science B.
