Abstract

The absolute alpha energy of

{Po}^{210}

alpha particles was measured by a 180° magnetic spectrometer. The value obtained was 5.3054±0.0010 Mev (absolute volts). Measurement of the energy (

α_{0}

) of the alpha particles from

{Cm}^{244}

leading to the ground state of

{Pu}^{240}

was made relative to the energy of the

{Po}^{210}

alpha particles. A value of 5.8025±0.002 Mev was obtained for this

{Cm}^{244}

α_{0}

energy. The energy difference between the ground state transition

α_{0}

and the transition

α_{1}

to the first excited level of

{Pu}^{240}

from

{Cm}^{244}

was found to be 43.5±1 kev.
