Abstract

We simultaneously measure the gravitationally-induced phase shift in two Raman-type matter-wave interferometers operated with laser-cooled ensembles of ⁸⁷Rb and ³⁹K atoms. Our measurement yields an E"otv"os ratio of η_Rb,K=(0.3± 5.4)× 10^-7. We briefly estimate possible bias effects and present strategies for future improvements.
