Single-photon loading of polar molecules into an optical trap
/ Schellenberg, Bart J (Nikhef, Amsterdam ; U. Groningen (main)) ; Prinsen, Eifion H (Nikhef, Amsterdam ; U. Groningen (main)) ; Nauta, Janko (CERN) ; Pašteka, Lukáš F (U. Groningen (main) ; Nikhef, Amsterdam ; Comenius U.) ; Borschevsky, Anastasia (U. Groningen (main) ; Nikhef, Amsterdam) ; Hoekstra, Steven (U. Groningen (main) ; Nikhef, Amsterdam)
We propose a scheme to transfer molecules from a slow beam into an optical trap using only a single photon absorption and emission cycle. [...]

Theoretical determination of the ionization potentials of ScF, YF, LaF, and AcF
/ Kyuberis, Aleksandra A. (Groningen U.) ; Pasteka, Lukas F. (Groningen U. ; Comenius U.) ; Eliav, Ephraim (Tel Aviv U. (main)) ; Sunaga, Ayaki (Eotvos U.) ; Au, Mia (CERN ; Mainz U.) ; Wilkins, Shane G. (MIT) ; Borschevsky, Anastasia (Groningen U.)
We present a comprehensive theoretical study of the ionization potentials of the MF (M = Sc, Y, La, Ac) molecules using the state-of-the-art relativistic coupled cluster approach with single, double, and perturbative triple excitations (CCSD(T)). We have further corrected our results for higherorder excitations (up to full triples), the QED self-energy and vacuum-polarization contributions. [...]

Opportunities for Fundamental Physics Research with Radioactive Molecules
/ Arrowsmith-Kron, Gordon (Michigan State U.) ; Athanasakis-Kaklamanakis, Michail (CERN ; Leuven U.) ; Au, Mia (CERN ; Mainz U.) ; Ballof, Jochen (CERN ; Michigan State U.) ; Berger, Robert (Philipps U. Marburg) ; Borschevsky, Anastasia (U. Groningen, VSI) ; Breier, Alexander A. (Kassel U.) ; Buchinger, Fritz (McGill U.) ; Budker, Dmitry (Darmstadt, GSI ; UC, Berkeley) ; Caldwell, Luke (JILA, Boulder ; U. Colorado, Boulder ; Colorado U.) et al.
Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei. [...]

The electron affinity of astatine
/ Leimbach, David (CERN ; U. Gothenburg (main) ; Mainz U., Inst. Phys.) ; Karls, Julia (U. Gothenburg (main)) ; Guo, Yangyang (U. Groningen, VSI) ; Ahmed, Rizwan (NCP, Islamabad) ; Ballof, Jochen (CERN ; Mainz U., Inst. Kernchem.) ; Bengtsson, Lars (U. Gothenburg (main)) ; Pamies, Ferran Boix (CERN) ; Borschevsky, Anastasia (U.

One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). Among the remaining elements with unknown EA is astatine, where one of its isotopes, $^{211}$At, is remarkably well suited for targeted radionuclide therapy of cancer. [...]

First Ionization Potentials of Fm, Md, No, and Lr: Verification of Filling-Up of 5f Electrons and Confirmation of the Actinide Series

We report the first ionization potentials (IP1) of the heavy actinides, fermium (Fm, atomic number Z = 100), mendelevium (Md, Z = 101), nobelium (No, Z = 102), and lawrencium (Lr, Z = 103), determined using a method based on a surface ionization process coupled to an online mass separation technique in an atom-at-a-time regime. The measured IP1 values agree well with those predicted by state-of-the-art relativistic calculations performed alongside the present measurements. [...]

The first ionization potential (IP1) of element 103, lawrencium (Lr), has been successfully determined for the first time by using a newly developed method based on a surface ionization process. The measured IP1 value is 4.9630.080.07 eV. [...]
