A Complete CDW Theory for the Single Ionization of Multielectronic Atoms by Bare Ion Impact
Atoms, 2021 A complete form of the post version of the continuum distorted wave (CDW) theory is used to investigate the single ionization of multielectronic atoms by fast bare heavy ion beams.

Ionization Time and Exit Momentum in Strong-Field Tunnel Ionization. [PDF]
Physical Review Letters, 2015 Tunnel ionization belongs to the fundamental processes of atomic physics. The so-called two-step model, which describes the ionization as instantaneous tunneling at the electric field maximum and classical motion afterwards with zero exit momentum, is ...

General phenomenology of ionization from aligned molecular ensembles
New Journal of Physics, 2015 Single and multi-photon ionization of aligned molecular ensembles is examined, with a particular focus on the link between the molecular axis distribution and observable in various angle-integrated and angle-resolved measurements.

Cavity-enhanced photoionization of an ultracold rubidium beam for application in focused ion beams [PDF]
, 2017 A two-step photoionization strategy of an ultracold rubidium beam for application in a focused ion beam instrument is analyzed and implemented. In this strategy the atomic beam is partly selected with an aperture after which the transmitted atoms are ...

Laboratory Photo-chemistry of PAHs: Ionization versus Fragmentation [PDF]
, 2015 Interstellar polycyclic aromatic hydrocarbons (PAHs) are expected to be strongly processed by vacuum ultraviolet photons. Here, we report experimental studies on the ionization and fragmentation of coronene (C24H12), ovalene (C32H14) and hexa-peri ...

Low ionization state plasma in CMEs
, 2012 The Ultraviolet Coronagraph Spectrometer on board the Solar and Heliospheric Observatory (SOHO) often observes low ionization state coronal mass ejection (CME) plasma at ultraviolet wavelengths. The CME plasmas are often detected in O VI (3x10^5K), C III
