First direct high-precision energy determination for the 8.4 and 20.7 keV nuclear transitions in Tm-169
Original language description
Energies of 8410.1 +/- 0.4, 20743.9 +/- 0.3, and 63121.6 +/- 1.2 eV were determined for the 8.4 keV M1 + E2, 20.7 keV M1 + E2, and 63.1 keV E1 nuclear transitions in Tm-169 (generated in the EC decay of Yb-169), respectively, by means of the internal conversion electron spectroscopy. The Yb-169 sources used were prepared by vacuum evaporation deposition on polycrystalline carbon and platinum foils as well as by ion implantation at 30 keV into a polycrystalline aluminum foil. The relevant conversion electron spectra were measured by a high-resolution combined electrostatic electron spectrometer at 7 eV instrumental resoluition. Values of 0.0326(14) and 0.0259(17) were derived from our experimental data for the E2 admixture parameter |delta(E2/M1)| for the 8.4 and 20.7 keV transitions, respectively. A possible effect of nuclear structure on multipolarity of the 20.7 keV transition was also investigated.
