Abstract
The absolute alpha energy of ${\mathrm{Po}}^{210}$ alpha particles was measured by a 180\ifmmode^\circ\else\textdegree\fi{} magnetic spectrometer. The value obtained was 5.3054\ifmmode\pm\else\textpm\fi{}0.0010 Mev (absolute volts). Measurement of the energy (${\ensuremath{\alpha}}_{0}$) of the alpha particles from ${\mathrm{Cm}}^{244}$ leading to the ground state of ${\mathrm{Pu}}^{240}$ was made relative to the energy of the ${\mathrm{Po}}^{210}$ alpha particles. A value of 5.8025\ifmmode\pm\else\textpm\fi{}0.002 Mev was obtained for this ${\mathrm{Cm}}^{244}$ ${\ensuremath{\alpha}}_{0}$ energy. The energy difference between the ground state transition ${\ensuremath{\alpha}}_{0}$ and the transition ${\ensuremath{\alpha}}_{1}$ to the first excited level of ${\mathrm{Pu}}^{240}$ from ${\mathrm{Cm}}^{244}$ was found to be 43.5\ifmmode\pm\else\textpm\fi{}1 kev.
