    Notes: Abstract The internal conversion coefficients were measured for the 88.032 keVE3 transition in109Ag using the 4π pressurized proportional counter, the windowless 4π scintillation counter and the double-focusing magnetic spectrometer. The results are:α T =26.4±0.4,α K =11.4±0.3, $$\alpha _{L_1 } = 0.63 \pm 0.13, \alpha _{L_2 } = 5.48 \pm 0.18, \alpha _{L_3 } = 6.11 \pm 0.20, \alpha _M = 2.40 \pm 0.08, \alpha _{N\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{O} } = 0.405 \pm 0.021$$ . The theoretical conversion coefficients were calculated for this transition and for the 391.69 keV M4 transition in113In and were found to be in agreement with the experiment.

    What atomic model should be used in internal conversion calculations? (1979)
    Springer
    The European physical journal 292 (1979), S. 399-400 
    Details

    Notes: Abstract Two sets of the internal conversion coefficients have been calculated using the Hartree-Fock-Slater and Hartree-Fock atomic models. The results of the latter model have been found to agree better with the experimental data.

    Internal conversion coefficients in the Hartree-Fock atomic model. Calculations and experiments for199Hg (1977)
    Springer
    The European physical journal 281 (1977), S. 347-353

    Notes: Abstract The internal conversion coefficients were calculated for the transitions in199Hg using both Hartree-Fock and Hartree-Fock-Slater atomic models. The relative conversion line intensities were measured with the magnetic spectrometers in Prague and Heidelberg. The multipolarities were determined to be:M1+(0.20±0.03)%E2, pure E2 and M 1+ (13.4 ±0.4)%E2 for the 50, 158 and 208 keV transitions, respectively. Allowing for the nuclear structure effect in M1 component we obtained: M1+(0.15±0.03) %E2,λ = 2.4±1.0 for the 50 keV and M1+ (10.9±0.7)% E2, λ=3.8±0.5 for the 208 keV transitions. Very good agreement was found between theory and experiment for the atomic subshells,K, L1−3,M 1−5,N, andO + P.

    Nuclear structure effect in internal conversion of the 166 kev hinderedM1 transition in139La (1977)
    Springer
    Czechoslovak journal of physics 27 (1977), S. 538-549

    Notes: Abstract The internal conversion coefficients were calculated for the 165.853 keV 5/2+→7/2+ hindered transition in 57 139 La using the new computer program NICC for conversion coefficients of all atomic shells. The algorithm employed in this code is described. The analysis of precise experimental data yielded the nuclear penetration parameterλ=4.2±0.8. This value was found to be in accord with theoretical estimates and to correspond to the Nilsson deformation parameterβ=−0.056±0004 of the139La nucleus. Using the Nilsson wave functions for aboveβ the mixing ratioδ 2 = Nγ(E2)/Nγ(M1) was determined to be less than 8.10−5, which supports the assumption of a pureM1 multipolarity of this transition.
