Abstract
We simultaneously measure the gravitationally-induced phase shift in two Raman-type matter-wave interferometers operated with laser-cooled ensembles of Rb and K atoms. Our measurement yields an E\"otv\"os ratio of . We briefly estimate possible bias effects and present strategies for future improvements.
