[en] Using the delayed coincidence technique, the following half lives have been determined for different excited states in ²³³U: T_1/2 (311.9 keV level) = (1.20 ± 0.15) x 10^-10 sec, T_1/2 (340.5 keV level) = (5.2 ± 1.0) x 10^-11 sec, T_1/2 (398.6 keV level) = (5.5 ± 2.0) x 10^-11 sec and T_1/2 (415.8 keV level) < 3 x 10^-11sec. From these half life determinations, together with earlier known electron intensities and conversion coefficients, 22 reduced B(Ml) and B(E2) transition probabilities (including 9 limits) have been deduced. The rotational transitions give information on the parameters δ and (g_K - g_R) . The experimental M1 and E2 transition rates between members of different bands have been analysed in terms of the predictions of the Nilsson model, taking also pairing correlations and Coriolis coupling effects into account
