Absolute Measurement of the Energy of Alpha Particles Emitted by 239Pu

  • Albrecht Rytz

Abstract

The spectrum of the alpha particles emitted by 239Pu has been investigated in considerable detail by several authors since 1948. The energy values corresponding to the various lines observed were determined with respect to well known standards. Table 1 gives a chronological summary of the reported energy values for the most intense transition.
