Modification of multipole transitions by twisted light
Sabrina. A. -L. Schulz, Stephan Fritzsche, Robert A. Müller +1
A theoretical analysis is presented for the excitation of single many-electron atoms and ions by twisted (or vortex) light. Special emphasis is put on excitations that can proceed…
Gravitational effects on geonium and free electron -factor measurements in a Penning trap
Sebastian Ulbricht, Robert Alexander Müller, Andrey Surzhykov
We present a theoretical analysis of an electron confined by a Penning trap, also known as geonium, that is affected by gravity. In particular, we investigate the gravitational inf…
Electronic level structure of in the range of the isomer energy
David-Marcel Meier, Johannes Thielking, Przemysław Głowacki +4
Using resonant two-step laser excitation of trapped ions, we observe 166 previously unknown energy levels of even parity within the energy range from 7.8 to 9…
Excitation of the Th nucleus via a two-photon electronic transition
Robert A. Müller, Andrey V. Volotka, Andrey Surzhykov
We investigate the process of nuclear excitation via a two-photon electron transition (NETP) for the case of the doubly charged thorium. The theory of the NETP process has been dev…
