VUV photoionization and dissociative photoionization spectroscopy of the interstellar molecule aminoacetonitrile: Theory and experiment

Atomic photoionization experiment by harmonic-generation spectroscopy

Experimental and quantum-chemical studies on photoionization and dissociative photoionization of CH2Br2.

The dissociative photoionization of CH2Br2 in a region approximately 10-24 eV was investigated with photoionization mass spectroscopy using a synchrotron radiation source. An adiabatic ionization energy of 10.25 eV determined for CH2Br2 agrees satisfactorily with predictions of 10.26 and 10.25 eV with G2 and G3 methods, respectively. Observed major fragment ions CH2Br+, CHBr+, and CBr+ show app...

Photoionization of metastable O+ ions: experiment and theory.

High-resolution absolute experimental measurements and two independent theoretical calculations were performed for photoionization of O+ ions from the 2P(o) and 2D(o) metastable levels and from the 4S(o) ground state in the photon energy range 30-35.5 eV. This is believed to be the first comparison of experiment and theory to be reported for photoionization from metastable states of ions. While...

Photoionization of Metastable O1 Ions: Experiment and Theory

High-resolution absolute experimental measurements and two independent theoretical calculations were performed for photoionization of O ions from the 2Po and 2Do metastable levels and from the 4So ground state in the photon energy range 30–35.5 eV. This is believed to be the first comparison of experiment and theory to be reported for photoionization from metastable states of ions. While there ...

Photoionization Suppression by Continuum Coherence: Experiment and Theory

We present experimental and theoretical results of a detailed study of laser-induced continuum structures (LICS) in the photoionization continuum of helium out of the metastable state 2s S0. The continuum dressing with a 1064 nm laser, couples the same region of the continuum to the 4s S0 state. The experimental data, presented for a range of intensities, show pronounced ionization suppression ...
