An independent determination of the binding energy of the deuteron
Rogers, Fred Terry, Jr

This paper is an account of an experiment designed to determine the binding energy of the deuteron by a method which is relatively insensitive to uncertainties in the energy-range relation for protons of low energy. The protons, produced by the disintegration of deuterium by Th C″ gamma-radiation, were observed in a low-pressure cloud chamber in a strong magnetic field. The curvatures of the tracks allowed the calculation of the corresponding kinetic energies. The final value of the binding energy as got by this experiment is VB=2.17+/- 0.05x106 electron-volts, which is in excellent agreement with the values previously got by Bethe (from the data of Chadwick, Feather and Bretscher) and by J. R. Richardson and Emo.
