摘要: K-Auger electrons ejected from the L and M levels of Ba137 are studied by means a double coil, magnetic lens beta-ray Spectrometer with thin Zapon film G-M counter. The kinetic energies those observed were compared values evaluated calculations Slater's system screening constants. relative intensities K-LL: K-LM: K-MN estimated to be 10:5.0±0.2:0.8±0.04 K fluorescence yield ω κ , 0.85±0.03.
