Photoelectron-photoelectron coincidence spectroscopy
Journal of Electron Spectroscopy and Related Phenomena, 1990Abstract Photoelectron-photoelectron coincidence spectra taken using a fixed-wavelength laboratory instrument show certain states of molecular doubly-charged ions. They are complicated, however, by a phenomenon of non-resonant autoionization, whose existence is now revealed.

PHOTOELECTRON QUANTUM YIELDS AND PHOTOELECTRON MICROSCOPY OF CHLOROPHYLL AND CHLOROPHYLLIN
Photochemistry and Photobiology, 1975Abstract— The absolute PE quantum yield curves of chls a and b,.chin, and phytol were examined over the wavelength range 500‐180 nm. In the long wavelength region (500‐240 nm) quantum yields are below 5 × 10‐6 electrons per incident photon. Below 240 nm the quantum yields rise sharply.

Photoelectron Diffraction and Photoelectron Holography
2013Photoelectron spectroscopy is mostly used for the analysis of electronic structures. ARPES is a powerful tool for band mapping and Fermiology as explained already. It is also widely known that the photoelectrons are diffracted by neighboring atoms and provide characteristic diffraction patterns.

Physical Review Letters, 2000
Experiments are reported on the detection of slow photoelectrons resulting from the photoionization of Xe atoms in a dc electric field by electron imaging. In the far-field photoelectron velocity distributions we can distinguish between direct and indirect ionization processes (involving long range Coulomb interactions with the Xe+ ion).

Photoelectron holography = holography + photoelectron diffraction
Journal of Electron Spectroscopy and Related Phenomena, 1990Abstract Photoelectron holography produces three dimensional images of surface sites with atomic scale (0.5A) resolution. While experimentally identical to two angle photoelectron diffraction, photoelectron holography is a true holographic technique. The atomic resolution images can be obtained by Fourier transformation.

Photoelectron spectra of polysilanes
Physical Review B, 1986Some organopolysilanes (high-molecular-weight polymers which only contain silicon atoms in their backbone) can be used as highly sensitive, self-developing uv photoresists. To understand the electronic structure of polysilanes and help rationalize their solid-state uv photosensitivity, we have recorded the photoelectron spectra of several polysilanes ...

Photoelectron spectroscopy of HC4N−
The Journal of Chemical Physics, 2011We report the 364-nm photoelectron spectrum of HC4N−. We observe electron photodetachment from the bent $\tilde X$X̃2A″ state of HC4N− to both the near-linear $\tilde X$X̃3A″ and the bent ã 1A′ states of neutral HC4N. We observe an extended, unresolved vibrational progression corresponding to $\tilde X$X̃3A″ ← $\tilde X$X̃2A″ photodetachment, and we ...

Inelastic photoelectron diffraction
Physical Review B, 1991Photoelectron diffraction and Auger-electron diffraction studies to date have involved the study of the elastically scattered or ``no-loss'' features in spectra. In this work, we consider the diffraction patterns associated with inelastically scattered electrons in plasmon satellites.
