The critical phenomena associated with electron localization-delocalization transitions along the dissociation path of the C4- anion was studied. The symmetrical and nonsymmetrical configurations of the linear C4- anion were isoenergetic at the equilibrium geometry. The net potential obtained in the classical limit provided a reliable heuristic model for electronic phase transitions. The model exhibited symmetry breaking analogous to both a first order and a continuous phase transition.
