Photodisintegration Thresholds of Deuterium and Beryllium

Abstract
The photodisintegration thresholds of deuterium and beryllium have been determined by using the bremsstrahlung produced by monoergic electrons. The absolute energy of the electrons was measured with a cylindrical electrostatic analyzer. The binding energy of deuterium was found to be 2.227±0.003 Mev and that of beryllium was found to be 1.662±0.003 Mev.
