TDPAC Studies of Local Defects and Phenomena in Ferroics and Multiferroics / Schell, Juliana (CERN ; Duisburg-Essen U.) ; Marschick, Georg (CERN ; TU Vienna)
We provide an overview of time-differential perturbed angular correlation (TDPAC) measurements of ferroic and multiferroic materials. Here, we explore chalcogenide spinels, lead titanate, lead zirconate, and bismuth ferrite, describing the use of TDPAC experiments to probe the physics of localized defects and the various mechanisms that govern electronic and magnetic interactions, the coupling of the associated degrees of freedom, and the structural, charge, and orbital correlations for these materials..

Laser-assisted nuclear decay spectroscopy of $^{176,177,179}$Au / Harding, R D (York U., England ; CERN) ; Andreyev, A N (York U., England ; JAERI, Tokai) ; Barzakh, A E (St. Petersburg, INP) ; Cubiss, J G (York U., England) ; Van Duppen, P (Leuven U.) ; Al Monthery, M (York U., England) ; Althubiti, N A (Manchester U.) ; Andel, B (Leuven U. ; Comenius U.) ; Antalic, S (Comenius U.) ; Cocolios, T E (Leuven U. ; Manchester U.) et al.
A study of the laser-ionized and mass-separated neutron-deficient isotopes $^{176,177,179}$Au was performed using the Resonance Ionization Laser Ion Source and the Windmill detection setup at ISOLDE, CERN. New and improved data on complex fine-structure α decays of the three isotopes were deduced, providing insight into the low-lying levels in the daughter nuclei $^{172,173,175}$Ir. [...]

Low-spin states in $^{80}$Ge populated in the $\beta$ decay of the $^{80}$Ga $3^-$ isomer / Sekal, S (Algiers U. Sci.

Lab.) et al.
The structure of  $^{80}$Ge has been investigated at the ISOLDE facility at CERN. A previous study reported for the first time a low-lying $0^+_2$ intruder state at 639 keV, based on the coincidence with a previously unobserved 1764-keV $γ$ ray, and suggested it as evidence for shape coexistence in $^{80}$Ge.

Porous Silicon as a Platform for Radiation Theranostics Together with a Novel RIB-Based Radiolanthanoid / Jakobsson, Ulrika (Helsinki U.) ; Mäkilä, Ermei (Turku U.) ; Airaksinen, Anu J (Helsinki U.) ; Alanen, Osku (Helsinki U.) ; Etilé, Asenath (Helsinki U.) ; Köster, Ulli (Laue-Langevin Inst.) ; Ranjan, Sanjeev (Helsinki U.) ; Salonen, Jarno (Turku U.) ; Santos, Hélder A (Helsinki U.) ; Helariutta, Kerttuli (Helsinki U.)
Mesoporous silicon (PSi) is biocompatible and tailorable material with high potential in drug delivery applications. Here, we report of an evaluation of PSi as a carrier platform for theranostics by delivering a radioactive ion beam- (RIB-) based radioactive lanthanoid into tumors in a mouse model of prostate carcinoma.

A generalized fitting tool for analysis of two-dimensional channeling patterns / David-Bosne, E (Lisbon U.) ; Wahl, U (Lisbon U. ; Leuven U.) ; Correia, J G (Lisbon U.) ; Lima, T A L (Lisbon U.) ; Vantomme, A (Lisbon U.) ; Pereira, L M C (Leuven U.)
The acquisition of two-dimensional (2D) channeling patterns is gaining increased popularity within the ion beam community. However, with the exception of emission channeling experiments for the lattice location of radioactive impurities, quantitative analysis of such patterns is rarely found. [...]

C‐terminal Cysteines of CueR Act as Auxiliary Metal Site Ligands upon Hg$^{II}$ Binding—A Mechanism To Prevent Transcriptional Activation by Divalent Metal Ions? / Balogh, Ria K (Szeged U.) ; Gyurcsik, Béla (Szeged U.) ; Hunyadi‐Gulyás, Éva (Szeged U., Cybernetics Lab) ; Schell, Juliana (CERN ; Duisburg-Essen U.) ; Thulstrup, Peter W (Copenhagen U.) ; Hemmingsen, Lars (Copenhagen U.) ; Jancsó, Attila (Szeged U.)
Intracellular CuI is controlled by the transcriptional regulator CueR, which effectively discriminates between monovalent and divalent metal ions. It is intriguing that HgII does not activate transcription, as bis-thiolate metal sites exhibit high affinity for HgII. [...]

Tin resonance-ionization schemes for atomic- and nuclear-structure studies / Gustafsson, F P (Leuven U.) ; Ricketts, C M (Manchester U.) ; Reitsma, M L (U. Groningen, VSI) ; Garcia Ruiz, R F (CERN ; MIT) ; Bai, S W (Peking U., SKLNPT) ; Berengut, J C (Heidelberg, Max Planck Inst. ; New South Wales U.) ; Billowes, J (Manchester U.) ; Binnersley, C L (Manchester U.) ; Borschevsky, A (U. Groningen, VSI) ; Cocolios, T E (Leuven U.) et al.
This paper presents high-precision spectroscopic measurements of atomic tin using five different resonanceionization schemes performed with the collinear resonance-ionization spectroscopy technique. Isotope shifts were measured for the stable tin isotopes from the $5s^2 5p^2$ $^3P_{0,1,2}$ and $^1S_0$ to the $5s^2 5p6s ^1P_1, ^3P_{1,2}$ and $5s^2 5p7s^1 P_1$ atomic levels. [...]

Laser-assisted decay spectroscopy and mass spectrometry of $^{178}\mathrm{Au}$ / Cubiss, J G ; Andreyev, A N ; Barzakh, A E ; Manea, V ; Al Monthery, M ; Althubiti, N A ; Andel, B ; Antalic, S ; Atanasov, D ; Blaum, K et al.
A comprehensive study of the isotope $^{178}$ Au has been made at the CERN-ISOLDE facility, using resonance laser ionization. Two long-lived states in $^{178}$ Au were identified—a low-spin ground state and a high-spin isomer—each of which were produced as pure beams. [...]

Thermal stability of interstitial and substitutional Mn in ferromagnetic (Ga,Mn)As / IS580 Collaboration
In (Ga,Mn)As, a model dilute magnetic semiconductor, the electric and magnetic properties are strongly influenced by the lattice sites occupied by the Mn atoms. In particular, the highest Curie temperatures are achieved upon thermal annealing in a narrow temperature window around 200°C, by promoting the diffusion of interstitial Mn towards the surface. [...]
