Abstract
We have performed a measurement of the Casimir Polder force using a magnetically trapped ^u87Rb Bose Einstein condensate. By detecting perturbations of the frequency of center of mass oscillation of the condensate perpendicular to the surface, we are able to detect this force at a distance proportional to 5 m, significantly further than has been previously achieved, and at a precision approaching that needed to detect the modification due to thermal radiation. Additionally, this technique provides a limit for the precense of exotic forces in the proportional to 1 m range.Citation
