Abstract

The γ‐spectrometry method for determination of the relative change ΔλEC/λEC in the partial probability λEC for the 114mIn decay branch by the electron capture (EC), when the nucleus is in different chemical environments, was developed. The method is based on an experimental determination of the relative change ΔIγ/Iγ in the intensity of the γ‐radiation which is emitted by the excited daughter 114Cd nuclei after EC. The 114mIn decay by EC in indium metal, In2O3 and InAs was compared. The largest ΔIγ/Iγ=(2.5±0.8)·10−4 has been found for InAs relatively to In2O3. The chemical changes in the electron density on the indium nucleus corresponding to the measured ΔIγ/Iγ values have been determined.
