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. [...]

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. [...]

The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without employing magnetic fields to transport or momentum filter the electrons. [...]

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. (iThemba LABS ; Western Cape U.) ; Guo, S. (Lanzhou, Inst.

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.

Nuclear moments of indium isotopes reveal abrupt change at magic number 82
/ Vernon, A R (Manchester U. ; MIT ; Leuven U.) ; Garcia Ruiz, R F (MIT ; CERN) ; Miyagi, T (TRIUMF) ; Binnersley, C L (Manchester U.) ; Billowes, J (Manchester U.) ; Bissell, M L (Manchester U.) ; Bonnard, J (York U., England) ; Cocolios, T E (Leuven U.) ; Dobaczewski, J (York U., England) ; Farooq-Smith, G J (Leuven U.) et al.
In spite of the high-density and strongly correlated nature of the atomic nucleus, experimental and theoretical evidence suggests that around particular ‘magic’ numbers of nucleons, nuclear properties are governed by a single unpaired nucleon$^{1,2}$. A microscopic understanding of the extent of this behaviour and its evolution in neutron-rich nuclei remains an open question in nuclear physics$^{3–5}$. [...]

(Campinas State U.) ; Fries, R.J. (Texas A-M ; Texas A-M, Cyclotron Inst.) ; Gustafson, G. (Lund U.) ; van Hees, H. (Frankfurt U.) et al.
This paper is a write-up of the ideas that were presented, developed and discussed at the third International Workshop on QCD Challenges from pp to A-A, which took place in August 2019 in Lund, Sweden. The goal of the workshop was to focus on some of the open questions in the field and try to come up with concrete suggestions for how to make progress on both the experimental and theoretical sides.
