Abstract
Conversion electrons of the 10.84 keV transition in206Bi were measured with the iron-free magnetic spectrometer. The conversion line of the valence shell was observed to be narrower than those of the inner ones. The computer program which optimizes the line profiles given numerically is outlined and used for the spectrum analysis. The studied transition was proved to be pure M1 with the nuclear structure parameterλ=1.7±0.7. The internal conversion coefficients were calculated using the relativistic Hartree-Fock model for neutral atoms as well as various isolated ions. Altogether, 15 different valence-shell configurations were considered. The prediction for the 6s 2/21 configuration (Bi3+) is in accord with the measured conversion intensities. This is consistent with probable chemical form Bi2O3 of bismuth atoms in the radioactive source.
