Production of $^{{129} \textrm{m}}$Xe and $^{{131} \textrm{m}}$Xe via neutron activation of $^{128}$Xe and $^{130}$Xe at ILL-RHF and NCBJ-MARIA high-flux reactors

The long-lived xenon isomers $^{{129} \textrm{m}}$Xe and $^{{131} \textrm{m}}$Xe are of interest for the GAMMA-MRI project, which aims at developing a novel imaging modality based on magnetic resonance of polarized unstable tracers. Here, we present the steps leading to and following the production of these two isomers via neutron irradiation of highly-enriched $^{128}$Xe and $^{130}$Xe gas samples at two high-flux reactors, the High-Flux Reactor (Réacteur à haut flux, RHF) at the Institut Laue-Langevin (ILL) and the MARIA reactor at the National Centre for Nuclear Research (NCBJ).

First β-decay spectroscopy of $^{135}$In and new $β$-decay branches of $^{134}$In
/ IDS Collaboration
The $\beta$ decay of the neutron-rich $^{134}$In and $^{135}$In was investigated experimentally in order to provide new insights into the nuclear structure of the tin isotopes with magic proton number $Z=50$ above the $N=82$ shell. The $\beta$-delayed $\gamma$-ray spectroscopy measurement was performed at the ISOLDE facility at CERN, where indium isotopes were selectively laser-ionized and on-line mass separated. [...]

$^{133}$In: A Rosetta Stone for decays of r-process nuclei

(Bucharest, IFIN-HH ; Leuven U.) et al.
The $\beta$ decays from both the ground state and a long-lived isomer of $^{133}$In were studied at the ISOLDE Decay Station (IDS). With a hybrid detection system sensitive to $\beta$, $\gamma$, and neutron spectroscopy, the comparative partial half-lives (logft) have been measured for all their dominant $\beta$-decay channels for the first time, including a low-energy Gamow-Teller transition and several First-Forbidden (FF) transitions.
