Abstract: The K-shell internal conversion coefficient (ICC) of 37 keV γ-transition in ¹²¹Sb decay was measured with high accuracy by the technique of γ- and K_X-spectroscopy; it is equal to α_К = 9.94 ± 0.12. Penetration parameter of M1-transition between states with Δl = 2 was determined on the basis of the obtained data as λ = -3.3 ± 0.8.
