We present moments and transition probabilities in the neighboring odd-mass nuclei of 208 Pb calculated fully self-consistently from the s.p. properties of 208 Pb with polarization corrections from its excitations, both given from previous Skyrme-Hartree-Fock and RPA calculations. The electric results agree nicely with the data with two very interesting exceptions. In the magnetic case we obtain similar results. We discuss also polarization contributions to the l-forbidden M 1 transitions, which are, however, much too small compared to the data. With a modified external field operator which accounts effectively for mesonic and many-body effects the description of the data can be substantially improved.

Detailed information on isomeric states in A ≈ 135 nuclei is exploited to benchmark shell-model calculations in the region northwest of doubly magic nucleus 132 Sn. The N = 79 isotones 133 Xe and 135 Ba are studied after multinucleon transfer in the 136 Xe + 208 Pb reaction employing the high-resolution Advanced GAmma Tracking Array (AGATA) coupled to the magnetic spectrometer PRISMA at the Laboratori Nazionali di Legnaro, Italy and in a pulsed-beam experiment at the FN tandem accelerator of the University of Cologne, Germany utilizing a 9 Be + 130 Te fusion-evaporation reaction at a beam energy of 40 MeV. Isomeric states are identified via delayed γ-ray spectroscopy. Hitherto tentative excitation energy, spin, and parity assignments of the 2107-keV J π = 23/2 + isomer in 133 Xe are confirmed and a half-life of T 1/2 = 8.64(13) ms is measured. The 2388-keV state in 135 Ba is identified as a J π = 23/2 + isomer with a half-life of 1.06(4) ms. The new results show a smooth onset of isomeric J π = 23/2 + states along the N = 79 isotones and close a gap in the high-spin systematics towards the recently investigated J π = 23/2 + isomer in 139 Nd. The resulting systematics of M2 reduced transition probabilities is discussed within the framework of the nuclear shell model. Latest large-scale shell-model calculations employing the SN100PN, GCN50:82, SN100-KTH, and a realistic effective interaction reproduce the experimental findings generally well and give insight into the structure of the isomers.

High-spin spectroscopy and shell-model interpretation of the N < 126 radium isotopes Ra212 and Ra<

The level structures of 212 Ra and 213 Ra have been established via time-correlated γ-ray spectroscopy following the 204 Pb( 12 C,4n) 212 Ra and 204 Pb( 13 C,4n) 213 Ra reactions. In 212 Ra, levels up to ∼ 6.2 MeV were identified and firm spin-parity assignments were achieved to a J π = 19 + isomer with a mean life of 31(3) ns. For 213 Ra the corresponding values were ∼ 4.5 MeV in excitation energy and J π = 33/2 + . Two isomeric states with J π = 23/2 + , τ = 27(3) ns and J π = 33/2 + , τ = 50(3) ns were discovered in 213 Ra. The experimental data were compared with semiempirical shell-model calculations, which allowed dominant configurations to be assigned to most of the observed levels.
