In 1960Robert Pound carried out together with his assistant Glen Rebka an experiment, thePound–Rebka experiment, using theMössbauer effect to measure thegravitational redshift of the radiation from agamma source in thegravitation field of planet Earth.[2][3] Pound and Rebka used atHarvard University the Jefferson tower, which is only 22.6 meters tall. The work was part of Rebka's thesis with Pound as thesis advisor.
