Photoionization of helium by attosecond pulses: extraction of spectra from correlated wave functions
Luca Argenti, Renate Pazourek, Johannes Feist +5
We investigate the photoionization spectrum of helium by attosecond XUV pulses both in the spectral region of doubly excited resonances as well as above the double ionization thres…

Multi-electron transitions induced by neutron impact on helium
M. Liertzer, J. Feist, S. Nagele +1
We explore excitation and ionization by neutron impact as a novel tool for the investigation of electron-electron correlations in helium. We present single and double ionization sp…
