Abstract
SARGENT1 discovered the relation between the disintegration constant of the radioactive elements which decay by emitting a particle and the upper limit of the continuous spectrum. He found that in the diagram obtained by plotting the logarithms of the disintegration constants against the logarithms of the upper limits, a straight line can be drawn through the points for RaE, MsTh2, ThC and RaC, and a curved line through the points for RaD, UX1, ThB, AcC, ThC and UX2. The points for AcB and RaB do not fall on either of these curves.
