Abstract :
Summary form only given, as follows.An experiment for G measurement based on a fibre suspended light pendulum swinging freely in vacuum is proposed. This seems to be a better sensor for gravitational metrology than the ones that have mostly been used and appears capable of yielding an accuracy of 10/sup -5/ on the determination of G.
