Resumen:
Resonance states of a two-electron quantum dot are studied using a  variational expansion with both real basis-set functions and complexscaling methods. We present numerical evidence about the criticalbehavior of the density of states (DOS) in the region where there areresonances. The critical behavior is signaled by a strong dependence ofsome features of the DOS on the basis-set size used to calculate it. Theresonance energy and lifetime are obtained using the scalingproperties of the DOS.
