Gamma Ray Spectroscopy of Mn⁵⁴

Abstract

Internal conversion electrons of 0.84 Mev gamma ray were measured by a two-directional focusing beta-ray spectrometer, and it was determined that E γ =837.9±0.3 kev and K / L + M =8.5±0.7. Weak gamma rays were searched, using scintillation counters, but no gamma ray was observed.
