Conversion electron and gamma ray measurements with electrostatic and Si(Li), spectrometers, respectively, revealed the existence of the eV E1 nuclear transition in with the M2 admixture less than . The full intensity of the transition was determined to be almost 100% per decay. Existence of the 7.7 keV transition in solves the problem of the `anomalously fast' first-forbidden EC, transition in decay and introduces substantial changes into the accepted decay scheme of . Energies of the 24.4(2) and 71.95(5) keV transitions in were also improved to and eV, respectively. For the 11.4(1) keV M1 transition in , we improved the transition energy as eV and determined the E2 admixture to be less than 0.6%. |
