Abstract
We describe a new experimental configuration suitable for observing th e topological phase of Aharonov and Casher in atomic systems. Using th is we have been able to show experimentally that the Aharonov-Casher p hase is both independent of velocity and proportional to electric fiel d and we have verified the predicted size of the effect with an accura cy of 4%.
