Phys. Rev. Lett. 69, 1722–1725 (1992)Test of g universality with a Galileo type experimentReceived 7 May 1992; published in the issue dated 21 September 1992 The results of an experiment searching for the difference Δg in the free-fall acceleration of aluminum and copper, in vacuum, obtained on the Earth in a differential Galileo type measurement are reported. Within the sensitivity of the measurement, Δg/g=7.2×10-10; no g universality violation has been observed. © 1992 The American Physical Society URL:
