Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
The electron affinity of astatine
David Leimbach, Julia Sundberg, Yangyang Guo +35
One of the most important properties influencing the chemical behavior of an element is the energy released with the addition of an extra electron to the neutral atom, referred to…
Laser spectroscopy of the 1001nm ground state transition in dysprosium
Dominik Studer, Lena Maske, Patrick Windpassinger +1
We present the first direct excitation of the presumably ultra-narrow ground state transition in atomic dysproium. By using resonance ionization spectroscopy…
Efficient and robust photo-ionization loading of beryllium ions
Sebastian Wolf, Dominik Studer, Klaus Wendt +1
We demonstrate the efficient generation of Be ions with a 60 ns and 150 nJ laser pulse near 235 nm for two-step photo-ionization, proven by subsequent counting the number of io…
Counting individual 41Ca atoms with a magneto-optical trap
I. D. Moore, K. Bailey, J. Greene +6
Atom Trap Trace Analysis (ATTA), a novel method based upon laser trapping and cooling, is used to count individual atoms of 41Ca present in biomedical samples with isotopic abundan…
