We study the transition between liquid and solid electron phases of a two-dimensional quantum dot by performing extensive full-configuration- interaction calculations. From the analysis of pair correlation functions we find evidence of localization for values of the dimensionless density parameter λ ≈ 4. © 2007 American Institute of Physics.
