Using internal conversion electron spectroscopy, improved energy 21 541.5 +/- 0.5 eV was determined for the 21.5keV M1 + E2 nuclear transition in Eu-151 populated in the electron capture decay of Gd-151 . This value was found to agree well with the present adopted value but is much more accurate. A value of 0.0305 +/- 0.0011 derived for the E2 admixture parameter from the measured conversion electron line intensities corresponds to the present adopted value. A possible effect of nuclear structure on the multipolarity of the 21.5 keV transition was also investigated.
