Double to tenfold M-shell photoionization of singly charged lanthanum ions
M. Looshorn, B. M. Döhring, P. -M. Hillenbrand +9
Using the photon-ion merged-beams technique at the PETRA\,III synchrotron light source, we have measured cross sections for double and up to tenfold photoionization of La ion…

Comparison between Jacobi-Anger and saddle point methods to treat Above-threshold ionization
Danish Furekh Dar, Stephan Fritzsche
We present a detailed comparison of theoretical approaches for modeling strong-field ionization by few-cycle laser pulses. The dipole approximation is shown to accurately capture i…
