Abstract: The secondary electrons of the near-zero energy (e_o), formed in sources ^152,154,155Eu and ¹⁵³Gd, used in spectroscopy of conversion electrons are investigated. On the base of (γ-e_o) - and (KX–e_o) coincidences the Z-characteristics Z=N(γ-e_o)/Nγ and Z_β/Z_ε for emission of e_o-electrons are determined depending on a nuclide, its environment, geometry of measurements and strength of an assembling electrical field. It was defined that in formation of e_o-electrons from β-decay of ¹⁵⁴Eu the unknown near-zero component participates.
