【Abstract】 The energies of γ-rays from some nuclides around 500 keV have been measured by a slithering comparison with the precisely known γ-energies of ¹⁹²Ir. The energies determined by this method are:477603.18（44） eV for ⁷Be, 511852.70（58） eV for ¹⁰⁶Ru, 514004.87（52） eV for ³⁵Sr,520399.01（63） eV for ⁸³Rb, 529594.48（69） eV for ⁸³Rb and 552551.14（68） eV for ⁸³Rb, From the correction of the previous experiment by using the new result, the value of electron mass is obtained as 510998.6±1.1 eV which is in good agreement with the recently adjusted value of electron mass.更多还原
