Phys. Rev. D 59, 042001 (1998) [6 pages]Determination of the Newtonian gravitational constant G with a nonlinear fitting methodReceived 17 April 1998; published 30 December 1998 The Newtonian gravitational constant G is determined by means of a high-Q torsion pendulum and the time-of-swing method, in which the period of the pendulum is altered by the presence of two 6.25-kg stainless steel cylinders. The nonlinear fitting method is used to extract the frequencies from the angle-time data of the pendulum. The resulting value of G is (6.6699±0.0007)×10-11m3 kg-1 s-2. © 1998 The American Physical Society URL:
