- The rotational band structure of Lr-255 has been investigated using advanced in-beam gamma-ray spectroscopic techniques. To date, Lr-255 is the heaviest nucleus to be studied in this manner. One rotational band has been unambiguously observed and strong evidence for a second rotational structure was found. The structures are tentatively assigned to be based on the 1/2(-)[521] and 7/2(-)[514] Nilsson states, consistent with assignments from recently obtained alpha decay data. The experimental rotational band dynamic moment of inertia is used to test self-consistent mean-field calculations using the Skyrme SLy4 interaction and a density-dependent pairing force.

- The decay chain of Fm-246 has been investigated employing the SHIP separator at GSI Darmstadt. The Fm-246 nuclei were produced via the Ar-40(Pb-208, 2n)Fm-246 fusion-evaporation reaction. Improved values of the half-life, T-1/2 = 1.54(4) s, and of the spontaneous fission branching ratio, b(SF) = 0.068(6), of Fm-246 were obtained. The beta(+)/electron capture branching ratio, b(EC) = 0.39(3), of Cf-242 was deduced. Possible structures of high-K states in Fm-246 are discussed within the framework of a model calculation based on the Woods-Saxon potential.
