    Notes: Abstract Excited states in127, 128Xe were populated in the reaction9Be+122Sn atE lab=38 MeV. The de-excitation of the isomeric states 7/2+ in127Xe and 8− in128Xe was studied using angular distribution and TDPAD methods on molten122Sn targets. The results are $$\begin{gathered} T_{1/2} (7/2^ + ) = 37 \pm 1 ns, g(7/2^ + ) = + 0.241 \pm 0.009 \hfill \\ T_{1/2} (8^ - ) = 83 \pm 2 ns, g(8^ - ) = - 0.036 \pm 0.009. \hfill \\ \end{gathered}$$ The experimentalg-factors suggest the main configurationsvg 7/2 andvh 11/2 g 7/2 for the isomeric states. Detailed analysis of the combined information fromg-factors and transition rates set stringent limits on the admixtures of the wave functions. The quasirotational bands built on the two-quasiparticle 6− and 10+ states are extended to higher spins, (14−) and (16+), respectively, and their structures are analyzed within the framework of the Interacting Boson Model.

    Notes: Abstract The current status of g-factor measurements of fission isomers is reviewed. In particular, we concentrate on magnetic and electric extranuclear perturbations affecting the fission isomers in solid environments. Recent results for isomers in237Pu and239Am are summarized and the single particle nature of these states is discussed.

    Notes: Abstract The method of perturbed angular distributions was used to measure the temperature dependence of the electric field gradient in Er single crystal for 98 K≤T≤156 K. The Iπ=11− isomer in Er154) was used as a probe. ω0 increases monotonically for 98 K≤T≤259 K and then decreases. A possible cause for this effect may be short range interactions between the f electrons above the Neel point.
