It is of interest to note that the slight discrepancy between the positions of the peaks and the energies of the [3-ray lines is much reduced by using the law Roc E01,82 to deduce the energies of the peaks. That shown at 29,000 volts is given an energy of 30,500 volts and that at 41,000 volts becomes 44,500 volts.
