Mainz, PRISMA) ; Nies, L (CERN ; Greifswald U.) ; Stegemann, S (CERN) ; Athanasakis-Kaklamanakis, M (CERN ; Leuven U. ; Imperial Coll., London) ; Cocolios, T E (CERN ; Leuven U.) ; Fischer, P (Greifswald U.) ; Giesel, P F (Greifswald U.) ; Johnson, J D (Leuven U.) ; Köster, U (CERN ; Laue-Langevin Inst.) ; Lange, D (Heidelberg, Max Planck Inst.) et al.
The radioactive nuclide 225225Ac is one of the few promising candidates for cancer treatment by targeted-αα-therapy, but worldwide production of 225225Ac faces significant limitations. In this work, the Isotope Separation On-Line method was used to produce actinium by irradiating targets made of uranium carbide and thorium carbide with 1.4-GeV protons. [...]

Detailed structure of Sn131 populated in the β decay of isomerically purified In131 states / IDS Collaboration
The excited structure of the single-hole nucleus Sn131 populated by the β− decay of In131 was investigated in detail at the ISOLDE facility at CERN. This new experiment took advantage of isomeric purification capabilities provided by resonant ionization, making it possible to independently study the decay of each isomer for the first time. [...]

On the nature of yrast states in neutron-rich polonium isotopes / IDS Collaboration
Polonium isotopes having two protons above the shell closure at Z=82Z=82 show a wide variety of low-lying high-spin isomeric states across the whole chain. The structure of neutron-deficient isotopes up to 210210Po (N=126N=126) is well established as they are easily produced through various methods. [...]

Proton-γγ coincidences from (d,p)(d,p) reactions between a 66Ni66Ni beam and a deuterated polyethylene target have been analyzed with the inverse-Oslo method to find the nuclear level density (NLD) and γγ-ray strength function (γγSF) of 67Ni67Ni. The 66Ni(n,γ)66Ni(n,γ) capture cross section has been calculated using the Hauser-Feshbach model in TALYS using the measured NLD and γγSF as constraints. [...]

Structural formation yield of GeV centers from implanted Ge in diamond / Wahl, Ulrich (IST, Lisbon (main)) ; Correia, João Guilherme (IST, Lisbon (main)) ; Costa, Ângelo (Leuven U.) ; Lamelas, Afonso (Aveiro U.) ; Amaral, Vítor (Aveiro U.) ; Johnston, Karl (CERN) ; Magchiels, Goele (Leuven U.) ; Tunhuma, Shandirai Malven (Leuven U.) ; Vantomme, André (Leuven U.) ; Pereira, Lino M C (Leuven U.)
In order to study the structural formation yield of germanium-vacancy (GeV) centers from implanted Ge in diamond, we have investigated its lattice location by using the β emission channeling technique from the radioactive isotope 7575Ge (t1/21/2 = 83 min) produced at the ISOLDE/CERN facility. 7575Ge was introduced via recoil implantation following 30 keV ion implantation of the precursor isotope 7575Ga (126 s) with fluences around 2 × 101212–5 × 101313 cm22.
