as given in Figure 10. Values along the three scales that are read off at points
which are connected by a straight line always represent a solution of our
equation that relates these quantities. The three scales represent the values
of t 0 , the period of intrinsic oscillations in seconds, of DE the energy thresh-
old in electron volts, and t and life span of a state in seconds. Since a de-
