Abstract

The transitional nucleus¹⁵²Eu has been studied using the (n, e), (n, γ), (n_res, γ), (n, γγ), (d, p), (d, t) and (p, d) reactions. The experiments have been performed at nine different laboratories. A model independent level scheme was established including 95 levels below 510 keV and nearly 900 transitions by combination of low energy transitions and reaction data. More than 20 additional levels result from gamma rays and/or charged particle reactions. The level scheme is interpreted in terms of the Nilsson model indicating that¹⁵²Eu is a deformed nucleus. Seven rotational bands and Nilsson configurations are established. An additional 27 rotational bands are tentatively or speculatively assugned. Gallagher-Moszkowski splittings are discussed. The neutron binding energy was determined as 6305.2±0.5 keV. The energy of the 9.3 h 0^- isomer is 45.599 keV. The lifetimes of four levels were measured. Nuclear Reactions¹⁵¹Eu(n, γ), E_n=thermal and resonance; measured E_γ, I_γ, E_c.e., I_c.e., γγ Coinc., γγΔt coinc.;¹⁵¹Eu(d, p), E=12MeV and 14MeV;¹⁵³Eu(d, t), E=12MeV;¹⁵³Eu(p, d), E =18MeV; deduced level scheme of¹⁵²Eu, J, π, T_1/2, cc, Nilsson configurations. Magnetic electron spectrometer, curved crystal spectrometer, Ge(Li) and Si(Li) detectors, magnetic spectrographs. Enriched targets.
