Eötvös Experiment and the Gravitational Red Shift, R.H. Dicke, Am. J. Phys. 28, 344 (1960) (Abstract)
The relation of the results of the Eötvös experiment to the equivalence principle is discussed. It is asserted that the equivalence principle is not established by the results of the Eötvös experiment. The type of discrepancy discussed could result in an anomalous gravitational red shift. Consequently, contrary to the conclusion of L. Schiff's arefilce [Am. J. Phys. 28, 340 (1960), this issue], redshift experiments are considered important.
