Abstract :
We present the results of a gravitational experiment which is based on a microwave resonator. The gravitational force of a test mass acting on the resonator is measured as a function of distance. No deviation from Newton´s law has been found and the gravitational constant G has been determined with a relative accuracy of 2.2/spl times/10/sup -4/ to be: G=(6.6724/spl plusmn/0.0015)/spl times/10/sup -11/ N m/sup 2/ kg/sup -2/.<>
