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.
