High Spin Structure in 123^{123}Xe

Excited states of the nucleus $^{123}$Xe have been investigated with the fusion–evaporation-reaction $^{110}$Pd($^{18}$O,5n)$^{123}$Xe at 86 MeV beam energy, the compton-suppressed Nordball-multidetector-system at the Niels-Bohr-Institute in Risø, Denmark. The level scheme of $^{123}$Xe was extended up to a level of tentative $53/2^+\hbar$. Four excited bands of 3-quasiparticle-character were observed. Analyzing the directional correlation information, we could assign spin- and parity-values to all observed bands in $^{123}$Xe. The observed band structures fit well into systematics of the neighboring nuclei $^{125}$Xe and $^{127}$Xe

A New High-Spin Isomer in ¹⁴⁵Sm

A new high-spin isomer in $^{145}$Sm was observed by in-beam $\gamma$-ray spectroscopy with the reaction at 127 MeV performed at the Nord ball multi-detector array in Roskilde. The excitation energy of the isomer was determined to be E_{\mbox{\scriptsize x}} = 11147~\mbox{keV}, and using the generalized centroid-shift method its half-life was found to be $T_{1/2} = (7.4 \pm 1.0)$ ns

High-spin levels in 147^{147}Tb

The high-spin states of $^{147}$Tb have been with regard to their spins. The data were obtained by in-beam $\gamma$-ray spectroscopy using the reaction at 152 MeV performed at the Osiris spectrometer in Berlin. We obtained multipole mixing ratios for 60 transitions, and level spins up to 67/2$\hbar$ are introduced
