An experiment to detect gravity at sub-mm scale with high-Q mechanical oscillators

Autor: Haiberger, L., Weingran, M., Wenz, H., Schiller, S.

Silicon double paddle oscillators are well suited for the detection of weak forces because of their high Q factor (about 10^5 at room temperature). We describe an experiment aimed at the detection of gravitational forces between masses at sub-mm dist
