Polycyclic Aromatic Hydrocarbons: Photoionization Efficiencies vs. HOMO-LUMO Gaps

, 2019
Polycyclic aromatic hydrocarbons (PAH’s) are relevant in many fields. Johansson and coworkers measured the photoionization-efficiency (PIE) curves for various PAH’s.

L-photoionization of atomic aluminium: production of

, 2002
Aluminium atoms undergoing soft X–ray irradiation produce multiply–ionized ions in excited states through inner–shell photoionization followed by radiationless transitions, i.e. Auger cascades. Photoionization of 2s–, 2p– and 3s subshells are considered

Analysis of Dissipation Mechanisms for Cesium Rydberg Atoms in Magic-Wavelength Optical Trap

Photonics
A magic optical dipole trap (ODT) can confine atoms in the ground state and a highly excited state with the same light shifts, resulting in a long-range coherent lifetime between them, which plays an important role in high-fidelity quantum logic gates ...

RevMexAA (Serie de Conferencias), 10, 30-33 (2001)

, 2007
Using photoionization calculations with dust, we model the high excitation infrared lines of NGC 6302. This object is a high excitation bipolar planetary nebula of Peimbert type I.

Photoionization and Opacity

, 2023
Opacity determines radiation transport through material media. In a plasma source the primary contributors to atomic opacity are bound-bound line transitions and bound-free photoionization into the continuum.

Photoionization and Dissociative Photoionization of Acetaldehyde in the 10.0–13.7 eV Range by Synchrotron Photoelectron Photoion Coincidence Spectroscopy

ChemPhysChem
AbstractPhotoionization and dissociative photoionization of acetaldehyde (CH3CHO) in the 10.0–13.7 eV energy range are studied by using synchrotron radiation double imaging photoelectron photoion coincidence spectroscopy (i2PEPICO). The X2A′ and A2A“ electronic states of CH3CHO+ as well as the Franck‐Condon gap region between these two states have been

Molecular frame reconstruction using time-domain photoionization interferometry

, 2017
Photoionization of molecular species is, essentially, a multipath interferometer with both experimentally controllable and intrinsic molecular characteristics.

Strong-Field Photoionization: Analysis of Overlapping Above-Threshold Ionization and Laser-Assisted Photoemission Structures

Physical Sciences Forum
We present a theoretical description of atomic strong-field photoionization. Specifically, we consider an atom driven by a combination of two electromagnetic fields: a high-frequency field assisted by an intense laser of lower frequency.
