Correspondence of electron spectra from photoionization and nuclear internal conversion
Electron energy spectra have been measured that result from K-shell ionization of Kr by two different mechanisms: (1) photoionization and (2) internal conversion in the decay of the isomeric state of Kr83. It is demonstrated experimentally that these spectra, including satellites on the low-energy side of the primary 1s-electron peak, are identical. A theoretical interpretation of the identity of
