The energy of the 2 + -> 0 + transition in 226 U has been measured as 81.3(6) keV and the energy of the 4 + -> 2 + transition in 254 No has been measured as 101.1(6) keV, both for the rst time, by means of electron spectroscopy. The results are close to the estimates of the energies of these transitions from earlier work. Absolute values of electromagnetic decay intensities have been measured for yrast transitions in both nuclei. |
