Atominterferometrie in statischen elektrischen Feldern

Abstract

Using a Borde atom-interferometer with a thermal atomic calcium beam, the shift of the interference structure in electric fields was studied. From the Stark shift of the intercombination line (4s4p "3P_1 - 4s"2 "1S_0) for the #pi# and the #sigma# transition the scalar and sensor polarizability of the 4s4p "3P_1 state were calculated. The measured Aharonov-Casher effect is by a factor of 10"3 smaller than the Stark effect and its measured value is close to the theoretically derived value. It is proposed to use the Borde atom interferometer for an optical frequency standard of high stability.
