Determination of the first ionization energy of polonium by resonance ionization spectroscopy – Part II: Measurement of odd-parity Rydberg states at CERN–ISOLDE / Fink, D A (CERN) ; Blaum, K ; Fedosseev, V N (CERN) ; Marsh, B A ; Rossel, R E (CERN) ; Rothe, S (CERN)
Polonium (Po) is one of the rarest elements in Earth's crust. None of its isotopes are stable and sufficient amounts for systematic experimental studies of its most fundamental properties are only available by artificial production. [...]

Precision Mass Measurement of $^{58-63}$Cr: Nuclear Collectivity towards the $N=40$ Island of Inversion / Mougeot, M. (CSNSM, Orsay) ; Atanasov, D. (Heidelberg, Max Planck Inst.) ; Blaum, K. (Heidelberg, Max Planck Inst.) ; Chrysalidis, K. (CERN) ; Day Goodacre, T. (CERN ; Manchester U.) ; Fedorov, D. (St. Petersburg, INP) ; Fedosseev, V. (CERN) ; George, S. (Heidelberg, Max Planck Inst.) ; Herfurth, F. (Darmstadt, GSI) ; Holt, J.D. (TRIUMF) et al.
The neutron-rich isotopes $^{58-63}$Cr were produced for the first time at the ISOLDE facility and their masses were measured with the ISOLTRAP spectrometer. The new values are up to 300 times more precise than those in the literature and indicate significantly different nuclear structure from the new mass-surface trend. [...]

Potassium self-diffusion in a K-rich single-crystal alkali feldspar / Hergemöller, Fabian ; Wegner, Matthias ; Deicher, Manfred ; Wolf, Herbert ; Brenner, Florian ; Hutter, Herbert ; Abart, Rainer ; Stolwijk, Nicolaas A.
The paper reports potassium diffusion measurements performed on gem-quality single-crystal alkali feldspar in the temperature range from 1169 to 1021 K. Natural sanidine from Volkesfeld, Germany was implanted with {}^{43}K at the ISOLDE/CERN radioactive ion-beam facility normal to the (001) crystallographic plane [...]

Mass-selective ion ejection from multi-reflection time-of-flight devices via a pulsed in-trap lift / Wienholtz, F (Greifswald U. ; CERN) ; Kreim, S (CERN ; Heidelberg, Max Planck Inst.) ; Rosenbusch, M (Greifswald U.) ; Schweikhard, L (Greifswald U.) ; Wolf, R N (Heidelberg, Max Planck Inst.)
A method for high-resolution mass selection is presented which makes use of a multi-reflection time-of-flight mass spectrometer with in-trap lift. The new method needs no additional gating or deflection components. [...]

Binding Energy of $^{79}\mathrm{Cu}$: Probing the Structure of the Doubly Magic $^{78}\mathrm{Ni}$ from Only One Proton Away / Welker, A (Dresden, Tech. U. ; CERN) ; Althubiti, N  A  S (Manchester U.) ; Atanasov, D (Heidelberg, Max Planck Inst.) ; Blaum, K (Heidelberg, Max Planck Inst.) ; Cocolios, T  E (Leuven U.) ; Herfurth, F (Darmstadt, GSI) ; Kreim, S (Heidelberg, Max Planck Inst.) ; Lunney, D (CSNSM, Orsay) ; Manea, V (CERN ; Heidelberg, Max Planck Inst.) ; Mougeot, M (CSNSM, Orsay) et al.
The masses of the neutron-rich copper isotopes Cu75–79 are determined using the precision mass spectrometer ISOLTRAP at the CERN-ISOLDE facility. The trend from the new data differs significantly from that of previous results, offering a first accurate view of the mass surface adjacent to the Z=28, N=50 nuclide Ni78 and supporting a doubly magic character.

Neodymium-140 DOTA-LM3: Evaluation of an In Vivo Generator for PET with a Non-Internalizing Vector / IS528 Collaboration
140Nd (t1/2 = 3.4 days), owing to its short-lived positron emitting daughter 140Pr (t1/2 = 3.4 min), has promise as an in vivo generator for positron emission tomography (PET). However, the electron capture decay of 140Nd is chemically disruptive to macrocycle-based radiolabeling, meaning that an in vivo redistribution of the daughter 140Pr is expected before positron emission. [...]

Study of the long-lived excited state in the neutron deficient nuclides $^{195,197,199}$Po by precision mass measurement / ISOLTRAP Collaboration
Direct mass measurements of the low-spin $3/2^{(-)}$ and high-spin $13/2^{(+)}$ states in the neutron-deficient isotopes $^{195}$Po, $^{197}$Po, and high-spin $13/2^{(+)}$ state in $^{199}$Po were performed with the Penning-trap mass spectrometer ISOLTRAP at ISOLDE-CERN. These measurements allow the determination of the excitation energy of the isomeric state arising from the $\nu$i$_{13/2}$ orbital in $^{195,197}$Po. [...]

The first experimental investigation of the electron affinity (EA) of a radioactive isotope has been conducted at the CERN-ISOLDE radioactive ion beam facility. The EA of the radioactive iodine isotope (128)I (t (1/2) = 25 min) was determined to be 3.059 052(38) eV. [...]
