Abstract
The Breit-Wigner phase of a wave function was obtained by measuring the int erference between two independent ionization paths of a molecule. The state of interest was present in only one of the paths, there by producing a pha se shift in the observed signal. An analytical theory was used to determine the phase of the wave Function from the observable.
