| Title: | Gravitational constant G measured with a superconducting gravimeter |

| Abstract: | We report in this paper the results of a measurement of the gravitational constant G obtained in a
laboratory at distances of about 1 m, using a superconducting gravimeter. The instrument measured the
gravitational effect due to an annular mass of about 280 kg moving up and down around the gravimeter.
The experiment yielded for the gravitational constant the value G 6:675 0:007 10 11Nm2=kg2
which agrees, within its uncertainty, with the last CODATA value. |
