Abstract
We suggest a mechanism for the sharp phase change in the transition-probability amplitude of electrons scattered through a quantum dot. The proposed mechanism is a single electron phenomenon that involves interference between the two-dimensional resonances of the quantum dot. The dimensionality of the problem plays a key role in our mechanism.
