A distorted-wave approach to the elastic scattering of twisted electrons
A. L. Harris, S. Fritzsche
The elastic scattering of spinless vortex electrons on realistic target atoms has been investigated. In particular, expressions are derived in different approximations for the elas…
Quadratic Zeeman and Electric Quadrupole Shifts in Highly Charged Ions
Jan Gilles, Stephan Fritzsche, Lukas J. Spieß +2
Recent advances in high-precision spectroscopy of highly charged ions necessitate an understanding of energy shifts of ionic levels caused by external electric and magnetic fields.…
Hanle effect for lifetime determinations in the soft X-ray regime
Moto Togawa, Jan Richter, Chintan Shah +16
By exciting a series of transitions in helium-like nitrogen ions with linearly polarized mono…
Interaction of vector light beams with atoms exposed to a time-dependent magnetic field
Shreyas Ramakrishna, Riaan P. Schmidt, Anton A. Peshkov +3
During recent years interest has been rising for applications of vector light beams towards magnetic field sensing. In particular, a series of experiments were performed to extract…
Coulomb excitation of hydrogen atoms by vortex ion beams
Anna V. Maiorova, Dmitry Karlovets, Stephan Fritzsche +2
Coulomb excitation of hydrogen atoms by vortex protons is theoretically investigated within the framework of the non--relativistic first--Born approximation and the density matrix…
