@article{Briatore1977EvidenceFT, title={Evidence for the Earth gravitational shift by direct atomic-time-scale comparison}, author={L. Briatore and Sigfrido M. Leschiutta}, journal={Il Nuovo Cimento B (1971-1996)}, year={1977}, volume={37}, pages={219-231} }

SummaryOn the basis of the height difference between the CNR cosmic-ray laboratory at Plateau Rosa, 3500 m, and Turin, 250 m above s.l., a direct measurement of the terrestrial gravitational shift has been made by the comparison of the time scales of two cesium beam atomic frequency standards of the Istituto Elettrotecnico Nazionale «Galileo Ferraris». The principle of equivalence predicts the effect Δt/t=−ΔU/c2=3.54·10−13, corresponding to the gain of the standard at mountain altitudes Δt/t=30… Expand
