Signatures of enhanced octupole correlations at high spin in $^{136}\mathrm{Nd}$ / Petrache, C M (CSNSM, Orsay) ; Minkov, N (Sofiya, Inst. Nucl. Res.) ; Nakatsukasa, T (Tsukuba U. ; Nishina Ctr., RIKEN) ; Lv, B F (CSNSM, Orsay ; Lanzhou, Inst.

Experimental signatures of moderately enhanced octupole correlations at high spin in $^{136}\mathrm{Nd}$ are indicated for the first time. The extracted dipole moments of two negative-parity bands are only two times smaller than those of the lanthanide nuclei with $N≈90$ which present well-established octupole correlations. [...]

Evidence against the wobbling nature of low-spin bands in $^{135}$Pr / Lv, B.F. (Lanzhou, Inst. Modern Phys. ; Beijing, GUCAS) ; Petrache, C.M. (IJCLab, Orsay) ; Lawrie, E.A.

Modern Phys. ; Beijing, GUCAS) et al.
The electromagnetic character of the $\Delta I=1$ transitions connecting the one- to zero-phonon and the two- to one-phonon wobbling bands should be dominated by an $E2$ component, due to the collective motion of the entire nuclear charge. In the present work it is shown, based on combined angular correlation and linear polarization measurements, that the mixing ratios of all analyzed connecting transitions between low-lying bands in $^{135}$Pr interpreted as zero-, one-, and two-phonon wobbling bands, have absolute values smaller than one.

(Jyvaskyla U. ; Liverpool U. ; Lund U.) ; Déchery, F. (IRFU, Saclay) et al.
Decay spectroscopy of the odd-proton nuclei $^{249}$Md and $^{251}$Md has been performed. High-$K$ isomeric states were identified for the first time in these two nuclei through the measurement of their electromagnetic decay. [...]

(Jyvaskyla U.) ; Calverley, T. (Jyvaskyla U. ; Liverpool U.) et al.
Two new bands have been identified in $^{137}$Nd from a high-statistics JUROGAM II gamma-ray spectroscopy experiment. Constrained density functional theory and particle rotor model calculations are used to assign configurations and investigate the band properties, which are well described and understood. [...]
